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
