Subject: AeroElectric-List: AC current reading for Revmaster engine
From: "Paul Eckenroth" <jeckenroth@nbn.net>


I have described previously the problems with my Revmaster engine and the destruction
of it's stator.  As I am slowly reassembling my firewall forward I've incorporated
a DC current sensor and various temperature sensors trying to create
an early warning system to catch a over temp and over current episode before
the stator is again burned up.  It occurred to me that rather than focusing
on the DC current I should be monitoring AC before it is modified by the voltage
regulator.  My GRT current sensor can be used for AC or DC but the GRT EIS
cannot process the AC generated signal. So, my question: can I modify the signal
from the sensor so that the EIS can give me a reading. Thanks for your help.

Paul

Measuring the AC current will only provide an indirect indication of high 
temperature, which can damage the stator windings.  You are better off 
measuring the stator temperature directly using thermocouples or 
thermistors or whatever is compatible with the GRT.  High AC current is not 
necessarily a problem unless it leads to high temperature.
