What is a Varmeter?Varmeter DefinitionA varmeter is defined as an instrument used to measure the reactive power in an electrical circuit.Single Phase VarmeterIn single-phase varmeters, the pressure coil voltage leads the coil current by 90 degrees, and the reading represents the reactive power.Polyphase VarmeterPolyphase varmeters use two auto-transformers in an open delta configuration to create a phase shift for measuring reactive power.Reactive Power MeasurementReactive power is crucial to me
