Issue: The ACCL is not having a display and when the incoming supply at ACCL EB terminal checked with multimeter not getting the proper voltage and coming 8.0 V R Phase to neutral, Y & N is 440, B & N is 440. Also checked at the incoming 4 pole MCB ...
IF meter is connected with 3 CT and 3 phase and meter is programmed for DELTA then A THD in Y PHASE Zero is displayed. How to over come A. Remove CT connected in Y phase B. Let all the CT be connected set STAR in setup.
Line current is the current through any one line between a three-phase source and load. Phase current is the current through any one component comprising a three-phase source or load. Fig: 1 STAR connection Line & Phase relation. Fig: 2 DELTA ...
Yes, we can connect 3 Phase Amp meter and KWH meter with the same CT. not need of separate CT for both meters. The same RYB CT's may connect to both meters for measurement. Please do the connection of CT to meters as explain below. R phase CT S1 ...
