Why 60Hz motor taking more current on load in 50Hz power
supply?
how much leakage current is allowed in MC61A L&T make relay?
What is EMC filter in VVVF Drive ?
Electromagnetic torque developed by the motor is compared to shaft torque. A less B same C depends on motor design D more
in case of three phase induction motor,when it is connected to three phase supply,why the magnetic field is rotets around the armeture?
What is a advantage of Self Reset Lockout ? On Fault breaker get trip & fault no longer exist then self reset lockout how inform us?
transformers? power factor? machiences?
what formula can be apply to calculate the No of rtrand of a cable. ?
any calculation method for decide cable size for current?
Sparking occur when a load is switched off because the circuit has high – a.) Inductance b.) Capacitance c.) Resistance d.) None
Under Ground Power cable earthing is required at both end or single end? and reason for the same
