What is the best thing to protect the motor from running over full current. CT or O/L or pressure transducer at the given pressure rating
how to calculate the earth fault current
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.
