Input Power Measurement System For Driving Motor In Testing Low-Speed Generator

Rapid technological advances are affecting the greater use of electrical energy. One devices that can generate energy is a generator. Testing characteristics generator required drive motor to rotate shaft. This research aims create three-phase input power measurement system for driving motor. The method measuring by current and voltage each phase. obtained from multiplication between voltage. consists sensors, signal conditioning circuit, an Arduino Mega microcontroller data processing. equipped with graphical user interface, storage, application. has been created tested. successfully measured generator's motor, which in real-time displayed on trend graph via interface laptop. time have stored inside micro-SD. average error reading 2% compared reference voltmeter. was meter ampere measurement.
