Abstract
Disclosed is an instrument transformer detecting an amount of power supplied to a load via a high voltage line, wherein the instrument transformer is integrally configured with a current level converter, a voltage level converter and a power amount calculating module so that it detects an amount of power supplied via the high voltage line and transmits the detected amount of power to a power amount management unit as a digital signal to correctly detect the amount of power.
Claims18
An instrument transformer, comprising:
- a current/voltage level converting unit which converts a level of current or voltage supplied to a load via a high voltage line to a low level;
- and
- a power amount calculating module which calculates an amount of power as an output signal of the current/voltage level converting unit.
An apparatus for detecting an amount of power using an instrument transformer, comprising:
- an instrument transformer calculating an amount of power supplied to a load via a high voltage line;
- and
- a power amount control unit controlling an amount of power calculated by the instrument transformer.
