Electrical Distribution and Power System Construction

Hello kylyn

1. Yes.

2. Yes.

It is not generally regarded as advisable to cross-install electrical equipment, because performance will suffer, along with longevity of the equipment.

There is another reason: 50Hz and 60Hz equipment generally have different voltage supply requirements.

Kind Regards....

Yes provided voltage and power rating are same.

Definitely.A 50Hz inductor will have a higher reactance and there higher impedance when installed in a 60HZ circuit and vice versa.Performance there fore suffers

what you should be aware of is that inductive equipment rated for 60Hz will have a lower reactance at 50Hz and so will draw more current at that frequency. This often leads to overheating and earlier failure. In the case of motors this problem is exacerbated by the fact that the motor and therefore it's cooling fan also will be running slower and thus providing less cooling.

XL= 2.∏.f.L

if f= 50 Hz, XL = 2.∏.50.L = 100.∏.L

f= 60 Hz, XL = 2.∏.60.L = 120.∏.L

in motor, if XL become higher , then current become higher too.

P = I².Z.cos Φ

P = I².(R+jXL).cos Φ

Z is impedance per phase---> so if XL increase, it cause P increase too
