    Hey guys,

    I want to calculate the current on the primary side of a 3 phase transformer. I have a 100kW load, the pri voltage is 25kV, the secondary voltage is 120/208V and assume a PF of 0.8. I'm just learning this stuff so any help is greatly appreciated.
    Thanks

    primary power = secondary power @100%efficiency, ideal coupling

    also i think primary is the LOW voltage side, or the input side

    IF your new with electronics and HV , and doing a teslacoil i'd suggest reading all those safety tips out there, including proper discharging..
    IF you are just testing a 3phase device you can get an ammeter
    OR you can just test current on 1 wire with an clamp-am and multiply it by 3
