at work we have a 3 phase motor but on testing one phase isnt getting a reading. it runs 24 hours a day all week. stops and starts well no noise or heating. the phase isnt down to earth.is it just a bad meter reading or not? phases one and three came up with a resistance reading of 0.4 but phase 2 couldnt get anything shows up as open circuit.
hi, i have 3x200KVA and 2 x 80KVA UPS with battery bank of 150AH 68Nos. and 100AH 204Nos., i need to install AC either ductable or PAC type, so can you help me to calculate heat load and capacity of the AC to install.
