Whether should be the oil level in OCTC transfomer? It should be upto winding immersed completely or should be upto tap changer s/w? How it will affect the performance of the transformer. Rating may be 33KVA
Can 4pole (3 phase+neautral )RCCB proper functioning in only 3 phase load (no neautral, no Earth) ?
standard earthing rating for power line..
Which standard we are following earthing resistance test
For refrigerators the motor current is raised beyond its rating on both conditions when the voltage of the system is more(say 270v) than the rated voltage(220v) as well as when the voltage of system is less(say 160v) than normal voltageof 220v, why explain?
Is there any rule to select the voltage of motor based on KW rating? What is the rating above which lt motor becomes the HT motor?.
