A-ET14 Three Phase Power Measurement by Three Watt Meter Method Trainer is an exclusive and useful product for Electrical laboratories. It is designed to explain the students, how total power is measured in a three phase circuit using three Wattmeters. With this product, student can study the power flow in three phase system and correspondingly calculate Active, Reactive and Apparent power. Apart from this student can easily understand different three phase parameters like Line Voltage, Line Current, Phase Voltage, Phase Current and their mutual relationships to verify star and delta properties in three phase circuit.
