Download Solution PDFThe connections of three-phase energy metre for measuring three-phase power, three wire energy is similar to the connections of _______.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe connections of a three-phase energy meter for measuring three-phase power, three wire energy is similar to the connections of a two wattmeter for power measurement
Two Wattmeter Method of Power Measurement
The total power measured by the wattmeter method is:
Energy meter for Energy Measurement
The energy measured by an energy meter is:
Similarities Between the Connections:
- Both the three-phase energy meter and the two-wattmeter method are typically used in a three-phase, three-wire system where there is no neutral wire.
- Both methods rely on two current coils to measure power in a three-phase, three-wire system.
- Both methods use voltage coils to measure the line-to-line voltage between phases.
- Both methods sum the power of two phases to calculate the total power in the system.
