Power Measurement Using Two Wattmeter Method

SKU: 9522 Category:

SALIENT FEATURES :

Power Measurement by Two Wattmeter Method is a versatile, self contained and standalone unit. It helps the students in understanding the different parameters like Line Voltage, Line Current, Phase Current, Phase voltage and their relationship in 3 Phase Star or Delta connected supply. It demonstrated the use of wattmeters in measuring power in a 3 phase circuit, study the power flow in three phase system and calculate Active, Reactive and Apparent power. The unit consists of various meters, resistive and Inductive load, etc all housed in an elegant powder coated metal cabinet with a well spread intelligently designed layout on front panel. The unit is accompanied with a comprehensive Instruction manual complete with theory, operating details, connection drawings and observation tables.
