Electrical Design specifications
Answer / me
Greetings all,
iam working in an out door lighting design for our plant
and i calculated the total watt needed (sum of all lights)
= 53 kw, 220 volt
our power supply is 480V
so, I chosed a 75 KVA transformer dry type 480/220-127 V 3
phase 60 Hz
cable size from feeder to transformer primary = 50 mm2 (1/0
AWG)
cable size from transformer secondary to distribution panel
board = 125 mm2 (250 MCM)
distribution panel board main breacker = 250 A
So, are my calculations ok ? any changes or suggestions ?
thanks in advance

When measuring the Insulation resistance of a motor winding (winding to earth) using a megger meter, Applied voltage(1000V) was automatically reduced to 500V. and the measured insulation resistance values are also very low (in Kohm range) Can anyone give me a reason???
Meggering minimum acceptable Ohms for insulation resistance.
