Q1: What is a volt amp meter?
A1: A digital volt amp meter is a high-precision, low-consumption, low-cost, portable, handheld, dual-channel input measuring instrument, specially designed for measuring voltage, current and phases on-site.
Q2: How a volt amp meter works?
A2: The volt-ampere meter adopts the clamp conversion method to input the measured current, so there is no need to disconnect the measured line during measurement. When measuring the phase between U1-U2, the two input circuits are completely insulated and isolated, thus completely avoiding the short circuit of the measured line caused by miswiring and burning the measuring instrument. This is the working principle of volt ammeters.
Q3: What can a volt amp meter do?
A3: When the circuit under test is not open, the volt ammeter can simultaneously measure two AC voltages, currents, phases between voltages, phases between currents, phases between voltages and currents, frequency, phase sequence, active power, reactive power, apparent power, power factor, etc., the volt amp meter can also identify the transformer wiring group, inductive and capacitive circuits, test the secondary circuit and bus differential protection system, read the phase relationship between the CTs of the differential protection groups, and check the watt-hour meter wiring and line equipment.
Tips: Volt amp meter applications in testing switch
If you think the switch is bad, you can test it using the ohmmeter function on a digital phase voltmeter (double clamp). With the breaker off and the switch off, set the volt amp meter to measure resistance and touch the probes to the switch terminals. When the switch is off, the resistance should be close to zero. If the resistance is high, it's time for a new switch.
