FAQ

250 kVA Transformer Load Capacity in KW

When the power factor = 1, it can carry 250KW. When the power factor=0.9, it can take 250x0.9=225KW.

The rated active power that the 250KVA transformer can connect to is: 250KVAx load power factor.

Of course, the transformer also allows appropriate overload, and the short-term overload can reach several times.

2. 250 kVA Transformer Current Rating

The rated current of the 250kVA transformer is 360A, that is, it can output a three-phase 360A current. The formula for calculating the rated current of the transformer is, input rated current: capacity/√3/input voltage rate, output rated current: capacity/√3 /output voltage.

For example: 10KV/0.4KV200KVA oil cooled transformer with an efficiency of 0.95, the maximum rated current of the high-voltage side is 12A, and the maximum rated current of the low-voltage side is 288A
