Mine MI-ET12 Single Phase Measurement by 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 Single phase circuit using wattmeter. With this product, student can study the power flow in Single phase system and correspondingly calculate Active, Reactive and Apparent power. Apart from this student can easily understand different Single phase parameters like Phase Voltage, Phase Current and their mutual relationships to verify Power in Single phase circuit.
