App description

Rated capacity refers to the customary value of apparent power under main tap. The capacity specified on the transformer name plate is the rated capacity, which means that the tap changer is located at the main tap, and is the product of rated no-load voltage, rated current and corresponding phase coefficient. For three-phase transformer, rated capacity = rated no-load line voltage × rated line current, and rated capacity is generally expressed in KVA or MVA. Rated capacity is the maximum capacity that can be continuously output during the specified normal service life, such as 30 years. The actual output capacity is the product of voltage with load (when inductive load, the voltage under load is less than rated no-load voltage), rated current and corresponding coefficient.

Load current refers to the actual stator current value detected when the motor drives the load, which changes with the size of the load.

Usage example

Rated capacity of batteries: 220 Milliampere hour

load current : 10 Milliampere

Click "Calculate" to output the result.

Estimate battery life: 15.399999999999999 hours.
