Low Power Factor Wattmeter - Definition & Construction

A low power factor (LPF) wattmeter is an instrument used to measure power in low power factor circuits. This type of wattmeters is employed for power measurement in circuits whose power factor is less than 0.5.      Generally, w…

Two Wattmeter Method of Power Measurement - Balanced Load

In the last article, we have seen the two wattmeter method of measuring three-phase power with an unbalanced load. In this, let us see the two wattmeter method with a balanced load. In a balanced three-phase system total power co…

Three Phase Power Measurement Using One Wattmeter Method

A wattmeter is an instrument used to measure the electrical power supplied in a circuit. It consists of a voltage coil connected across the load and a current coil connected in series with the load. So that deflection of the poin…
