IN THE CASE OF AN ELCB, IF THERE IS ANY UNSTABILITY BETWEEN PHASE AND NEUTRAL IT MAY TRIP. BUT MY QUESTION IS WHEN A LOAD IS CONNECTED IN BETWEEN P AND N, THE LOAD CONSUMES SOME POWER AND THERE IS A DIFFERENCE IN NEUTRAL WITH RESPECT TO THE PHASE. THUS ACCORDING TO ME, THE ELCB WILL AUTOMATICALLY OPERATES WHEN EVER THE LOAD CONSUMES-- I KNOW IT IS WRONG. BUT THE SOLUTION IS?????????
while we select CT, why the CT ratio is divided by 5?? ex:250/5,15VA,CLASS-1 CT.Why it is divided by 5??Help me please2 3306

WE HAVE A PROBLEM THAT THE MAIN DRIVE OF OUR CEMENT MILL HAS AN EARTHING PROBLEM?TWO OF STATOR WINDINGS INSULATION HAS BEEN COLLAPSED DUE TO AGING PROBLEM.THE PHASES HAVE BEEN BYPASSED AND NOW THE LOAD HAS BEEN INCREASED.WE CAN'T REPLACE THE MOTOR.KINDLY HELP ME BY GIVING SUGGESTION THAT HOW TO MAINTAIN THE STARTING TORQUE AND CURRENT FOR HIGH LOADS.
Kindly give the brief explanations for checking 12.5 kvar 440V, 25 KVAR 440V, 12.5KVAR 690V, 25 KVAR 690V capacitors microfarad values. what is the microfarad values for the above four type of capacitors, and give the formula explanations briefly. I know F-50HZ, voltage, and capacitor.1 3463
