That's double failure in single tank of gas . . . exceedingly
unlikely. Recommend your ov protection be on main bus and
voltmeter (or instrument containing voltage display function)
run from e-bus.

No, that lead is also the regulator's v-sense lead.

<etienne.phillips@gmail.com>
Hi Rick
Putting an OV module upstream of the regulator when using a permanent
magnet alternator is very likely to trip incessantly, as the regulator
keeps the voltage correct by dissipating the extra energy as heat,
unlike a field-coil alternator that actively modifies the voltage
generated by the alternator.
Etienne's assertions are based on the earliest marketplace
examples of rectifier regulator for PM alternators. The PM
alternator goes wAAAyyyy back in the history of electrical
systems on small engines where folks wanted to add things
light lighting and self starting to scooters, bikes,
and lawn care equipment.
Indeed, these alternators were seldom rated for more than
5-10 amps at max RPM (in a 6v system). The simplest means for
controlling their widely variable output voltage was to simply throw
a shunt load on the device to prevent excess energy from
making it out onto the system.
Of course, this means that the rectifier/regulator had to
be capable of turning 100% of the alternator's output
into pure heat under all conditions. So the heat dissipating
abilities of the R/R had to accommodate 50-100 watts of
output.
As the systems needing simple, low cost power matured the
the alternators were up-sized to accommodate design goals.
One can buy 3-phase, 30A PM machines today . . . but the
regulators are most certainly not capable of sinking all
that power. The reason is that SHUNT regulation has been
pretty much abandoned for SERIES regulation wherein
excess energy is kept off the system not by sinking it
to ground but by disconnecting the energy source from the
rest of the system.
This means that alternators are now taxed only as
the system demands can use the energy . . . before, the
alternator always ran flat-out and was necessarily
hot all the time. Exemplar schematics for modern rectifier/
regulators can be viewed here . . .
http://aeroelectric.com/Pictures/Schematics/3-Phase_PM_Rectifier_Regulator.gif
http://aeroelectric.com/Pictures/Schematics/PM_Regulator/Kubota_Schematic.jpg
For that reason, I wouldn't think that it's possible to have an OV
event, other than with a regulator failure, and the only way to catch
that would be to stick the OV relay and module downstream of the
regulator, after the rectification has happened, and when you're
dealing with DC.
The original idea for adding OV protection to the SD-8
DID put the disconnect relay downstream of the R/R. But
this didn't really comport with design goals for all
other OV protection systems . . . shut off the flow of
energy at the source. This is what prompted moving
the relay from the downstream side of R/R to the upstream
side in the AC wiring.
Now on a different note, wouldn't it be a good idea to stick the OV
relay upstream of the smoothing capacitor? I've seen one of those
70,000uF caps explode due to too much juice, and it's quite
impressive! My thinking is that if your regulator goes off the hook
and supplies the cap with 40V (or whatever the permanent magnet
alternator can generate), and that thing explodes in the cockpit, the
pilot is going to need a new set of underwear...
You need to abuse these guys pretty badly to achieve
such spectacular failures. Certainly a runaway 30A
alternator would be classified as pretty abusive.
Hence, putting the OV disconnect in the upstream
AC wiring affords the capacitor the same degree of
OV protection as the rest of the electro-whizzies
on the airplane.

ABSOLUTELY! I have SVLA instrumentation batteries that have
been kept on maintainers when not in service. Some are pushing
6-7 years old and they still deliver a hefty percentage of
like-new energy.
There's no reason that a well cared for battery in an
airplane cannot offer a very long service life. But the
phrase "well cared for" has a cost of ownership value.
You need to have a preventative maintenance plan that
calls for test equipment and $time$ along with an
attitude that encourages due-diligence on the part of
the owner-operator (YOU) to implement the plan.
In the air-transport and other commercial applications
for airplanes, there are usually folks on staff who are
paid for their due diligence and are outfitted with
the necessary tools. Compare this situation with the
C-172 that sits unattended for long periods of time,
perhaps a long way from an AC mains connection, owned
and operated by a guy who probably understands less
about his airplane than he does about his car or
bass boat.
The yearly change-out idea grew from the notion that
readers here on the List know far more about
their machines. It was further considered that many
would be attracted to the idea of treating batteries
like razor blades. Buy the least expensive and change
out often. This ASSURES in-flight performance while
MINIMIZING taxation of time, talent and resources
to keep battery-only operations confidence levels
high.
Now, if one is enamored of the notion for fitting
premium battery(ies) to their airplane, then indeed
the idea of yearly swap-out is problematic in
for achieving the lowest cost of ownership. So
your choices now are very clear.
(1) Shoulder the costs of NOT KNOWING just how good
or bad your battery might be in terms of meeting
battery-only design goals . . . and swap 'em out.
OR . . .
(2) Acquire tools and adopt a program that replaces
the convenience of yearly swap-out with a performance
assurance plan.
The decision is one that only you can make. I have
the tools and talent necessary to make my airplane
batteries well cared for. But if it were my airplane,
I'd opt for the yearly swap-out of inexpensive
batteries . . . but that's because I have better things
to do with my time than pray over batteries.

Subject: | Re: Z13-8 questions |
Tom,
> can the bus voltage sense lead be placed on the E-bus
The E-bus is fed through a diode which drops the voltage by about 1 volt. If the
regulator senses the E-bus voltage, then the regulator will try to keep the
E-Bus at 14 volts. The main bus will be 1 volt higher at over 15 volts. Operating
at over 15 volts will shorten the life of the battery and the devices connected
to the main bus.

The fusible link is located above the battery contactor.

Subject: | Re: OV Protection for Three-Phase PM Alternator |
Bob and Etienne, thanks for your replies. You've shed some light on a controversy
that erupted on the CorvairCraft list (on mylist.net) early this month: somebody
started bad-mouthing PM alternators and as evidence he cited several instances
of blown smoothing capacitors on Rotax installations. The thread got
bogged down in ad hominem attacks and counter-attacks and eventually was dropped
without resolving the question of why the capacitors had blown, but it appears
in light of what you two have pointed out that those setups must have had
the capacitors upstream of their OV protection -- or no OVP at all...
...Which leaves me puzzled with respect to the Z-figures' treatment of smoothing
capacitors with PM alternators: only Z-9 and Z-16 show them downstream of the
OVP; Z-10/8, -13/8, -17, -20 and -21 all have the capacitor upstream of the
OVP. The guy stirring things up on CorvairCraft confirmed that failures of these
caps are indeed spectacular. How likely to hear such a bang are users of
Z-10/8 et al?
Am I right in concluding that my best bet for minimizing the probability of an
unhappy ending with a three-phase PM alternator is to put a single disconnect
relay in the DC line downstream of the R/R but upstream of the smoothing capacitor,
leaving the R/R to fend for itself?

Hard to tell . . . mostly because they were using
hardware that has not been as well evaluated for
behavior as the SD-8 and regulators supplied by
B&C.

No . . . best-we-know-how-to-do is disconnect the
offending energy flow AT ITS SOURCE . . . break the
AC leads. The Z-figures have not been all updated
to this idea . . . but unlike the larger, 3-phase machines,
and the 18A system on Rotax, the SD-8 on a vacuum pump
pad doesn't represent much of a hazard to the smoothing
capacitor. Alternators that run much faster (higher
open circuit voltage) are another matter entirely.
By the way, you can leave this capacitor off if you
wish . . . it's value is problematic. See:
http://www.aeroelectric.com/Pictures/Curves/SD-8_Noise_Data.pdf
Note that some of the plots are at 50 mv/division vertical
scale, others are at 200 mv/division.

Mike, I had a similar problem. Discovered I had two sets of e mail rules
for dumping list e mails into my aeroelectric mail folder. So each time
the browser rule checker got triggered, it dump a copy (two total). I
deleted one of the rules and now only one copy. Don't know if that would
apply to your problem, but if you use rules, you might check it.

Subject: | Re: OV Protection for Three-Phase PM Alternator |
My recollection is that these Z diagrams have gone through changes over
time as design goals have evolved. I think I remember seeing some of the
PM diagrams without capacitors even. Some systems aren't very sensitive
to alternator noise.. Components never installed never fail.
I'd guess that the vast majority of PM alternators run for the life of the
airplane so long as the components are held to reasonable temperature and
the wiring is done correctly. Similarly, the output voltage of the
unregulated PM alternator isn't _that_ high - <100V. You can pick a cap
that can stand the full output and not worry about it failing should the
regulator pack it in. I see caps rated to (and above) 100V on the digikey
site for reasonable prices.

Thanks a bundle Ed. I had 2 extra rules sending the same thing to my
aeroelectric folder.(How they got there I do not know!)
All ok now.

Yeah, Mike, the double messages kept doing it to me for most of a year,
until I finally got so fed up I went searching for the problem. Never
figured it was that simple (once you find it {:>). My browser has a mind of
its own. Glad it fixed the problem

Subject: | Re: OV Protection for Three-Phase PM Alternator |
At 11:42 AM 1/26/2010, you wrote:
My recollection is that these Z diagrams have gone through changes over
time as design goals have evolved. I think I remember seeing some of the
PM diagrams without capacitors even. Some systems aren't very sensitive
to alternator noise.. Components never installed never fail.
I don't recall that. Until I did the noise studies we just
"assumed" that the single phase rectified output from the
SD-8 was going to be exemplar ordinarily noisy and adding
a capacitor was a good thing to do. Rotax and others had
been doing it for some years prior.
The surprise was that the SD-8 without a capacitor generated
no more noise than other devices qualified under mil-std-704
design goals that allow up to 1.5 v pk-pk conducted noise
in certain frequency ranges. See figure 15 in
http://www.aeroelectric.com/Reference_Docs/Mil-Specs/Mil-Std-704_excerpts.pdf
I'd guess that the vast majority of PM alternators run for the life of the
airplane so long as the components are held to reasonable temperature and
the wiring is done correctly. Similarly, the output voltage of the
unregulated PM alternator isn't _that_ high - <100V. You can pick a cap
that can stand the full output and not worry about it failing should the
regulator pack it in. I see caps rated to (and above) 100V on the digikey
site for reasonable prices.
True. However the majority of catastrophic failures I've
put my hands on were the result of hooking the capacitor
up backwards. And the SD-8 turning at 4,000 rpm on a vacuum
pump pad isn't a snarling monster either. Getting OV
protection sensed downstream of the capacitor and cutting
power upstream of the R/R seems to be the elegant solution.

Hi Rick and Bob
I realize now that I didn't get the picture in my mind across very
clearly at all! Agreed that the actual break in the circuit should be
as far upstream as possible, but the sensing should happen downstream
of the regulator, as you have explained. Apologies for confusing the
matter...
As for the cap disintegrating, my fears are put at ease if the relay
disconnects the source upstream of the regulator.
Thanks
Etienne

Adel clamps
Good call on aircraft spruce...didn't realize they did that.
Neal, I'm slowly going through some old fuel line, air line and smoke system clamps,
not to mention some electrical wire runs. Right now I can't be specific
on sizes and clamp layout until I get going on this.
Thanks for the offer.

Subject: | CD ROM as a cup holder, no joking. |
Has anyone converted a CD ROM to a retractable cup holder for use in their
aeroplane?
Details would be appreciated.
I just spent the last
week hanging instrument module on my Europa XS and need to mutilate it a
bit with an access panel. There is a place where a retractable cup holder
would be a nice feature so a little more mutilation would not be a
problem.I am thinking a gutted and mutilated CD ROM would not be too
heavy and way kool.
Thx.

There was a Coke a Cola bit of software going around about 10 years ago,
advertised as a free cup holder. You clicked on the link and your CD drawer
opened. Cute. It may have been associated with a virus, though.

Hi Ron,
My 2000 Subaru Imprezza had a dash board retractable cup holder. Quite
a bit lighter than
any cd-rom i've come across. Keep in mind that IT support folks
generally *learn* about
these little stories *after* the abused computer item fails in it's
non-intended role. It's not
the misuse that makes these on-the-job stories funny, it's the
indignation of the person
demanding why the cup holder broke after just 3 weeks that makes it
difficult not to laugh.
Oh, the Subaru part actually does a decent job. They are probably
cheap if you're
willing to go to a breaker's yard and work out some stress extricating
it. Ummm.. I'm
not sure my sube was a 2000 model though, sorry about that.
c'ya,
Michael
