    Ze/Zs of 3 phase supply

    Hey all, going over some testing before my final assesment. i've heard a couple of times when testing a 3 phase supply using a single phase to earth test you double the reading as your Ze/Zs, so if you test L1-E=0.07 Zs=0.14. also what i have done until now is test all three Lines to earth and...

    Pfc - pscc on 3 phase supplies

    Hi, Guys,when measuring PFC-PSCC on 3 phase supplies,I know that you test between live conductors L1-L2, L1-L3, L2-L3 and then all 3 to Neutral and note lowest reading obtained. Then all 3 phases ( is that right term for C&G? ) to earth. Then neutral to earth and lowest reading obtained recorded...

    3 phase pfc

    How do you continuity test a motor circuit to obtain Zs

    Hi, I can't seem to get my head around how to test a 3 Phase Motor circuit to obtain the value of Zs. 1. After isolation of circuit and locking off u short out the 3 Phases on the motor terminal block with shorting straps. 2. At the Dist Board with a Low Ohm meter you test the resistance...

Now when you get the reading on your meter (which is sometimes displayed with the Zs value)...
