Help please -- what do these ratings mean on a transformer?

[ianeaton230572]

Could anyone explain what the following ratings mean on a transformer?
120kw load, 1000v/500v, 60Hz

Welcome to PF!

maximum load is 120kw, input voltage is 1000v steps down to output voltage 500v AC at 60Hz

120 kW can't be labeled rating of a transformer. 120 kVA can.

120 kW can't be labeled rating of a transformer. 120 kVA can.

Yeah, I saw that too when I researched it and thought maybe its an old way to rate transformers or some wattage that you shouldn't exceed when you place a load on it.

The ratings on a transformer provide important information about its capacity and capabilities. In this case, the first rating of 120kw load refers to the maximum amount of power that the transformer can handle. This means that it is able to convert up to 120 kilowatts of electrical power.

The second rating, 1000v/500v, is known as the transformer's voltage ratio. It indicates the ratio between the input voltage (1000 volts) and the output voltage (500 volts). This means that the transformer is designed to convert high voltage electricity (1000 volts) into lower voltage electricity (500 volts).

Finally, the frequency of 60Hz refers to the rate at which the alternating current (AC) cycles in the transformer. This is important because different countries and regions use different frequencies for their electricity, and the transformer must be able to match the frequency of the power source in order to function properly.

Overall, these ratings provide important information about the capacity, voltage, and frequency capabilities of the transformer, which are crucial factors in determining its suitability for a specific electrical system. I hope this explanation helps to clarify the meaning of these ratings on a transformer.
