Can a capacitor compensation be connected to the output terminals of a motor soft starter?
Thread Content
There are 5 185KW low-voltage motors equipped with soft starters. The current drawn is currently 325A. YJV2x95 cables are being used, and the surface temperature of these cables is 65 degrees, which is a bit high. It is considered to install capacitors at the motor terminals as a means of compensating for this, in order to reduce the cable temperature. Is this approach appropriate?
Seems like this group is really quiet? ! The pandemic hasn’t led to lockdowns here either:P
Capacitive compensation certainly has its benefits, but it isn’t meant for cooling purposes. I’m afraid that installing capacitive compensation won’t be very helpful in cooling the cables. Installing reactors at the electrical cabinet end, on the other hand, can help increase the load-carrying capacity
The maximum temperature for YJV is 90 degrees; 65 degrees is quite normal, isn’t it?
90 is the temperature of the cable core, which is much higher than that of the outer layer
I’m not quite sure; could you provide more details?
Motors can be compensated on-site, which helps to reduce reactive current and losses; refer to GB 50052-2009 for details
Are there any specific implementation plans, examples, and precautions?
