I want to ask a question which i faced during testing of Capacitive Voltage Transformer in AIS. We have measured the C1 , C2 individually , but when we start to measure the total C1+C2 , the testing equipment shuts down and says low loading. Kindly is it possible to find the total capacitance by using measuring device. kindly briefly explain the procedure.

An 8 pole, 50 Hz, 3-phase IM is loaded to a poing where pull
out torque will occur. The rotor resistance per phase is 0.3
ohm and motor stalls at 650 rpm. The rotor reactance at
stand still is
A 2 ohm B 1.25 ohm
C 3.15 ohm D 2.25 ohm

What test must you do before powering up a circuit that you
have been working on?
need to make a report. Need to choose a 3phase induction
motor. Load conditions motor will operate in :
Maximum Load: 30 Kw
Speed: 2950 rpm
Ambient temp: 20 cent
Supply voltage: 440V
need to look for the safety factor when choosing the motor,
went through catalouge found a few, but dont know how to
choose the safety factor allowing an extra load something
above 30 KW to avoid any harm.
