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.
If a HV Underground Cable (13.8KV) is layed in the ground below 1.5 Mtrs and any building construction is done on the Cable route. IS this allowable or Not? What should be the clearance. As per ISO construction on HV cable route is safe or Not? Why? Can any body suggest the site for my question?
