Insulation Tester Earth Tester AC Clamp Meter AC / DC Clamp Meter Clip-on Power Factor Meter & Watt Meter Multimeter Electric Motor Checker A.C. High Voltage Breakdown Test Set Phase Sequence Indicator

 

Application
Measurement of power factor in AC system on L.T. Circuits having higher current load without interrupting circuit.

These instruments are very simple and convenient to operate as described below:

1. SINGLE PHASE CIRCUITS :
Connect potential between Neutral and line and clamp over 'Line' cable The instruments will read the respective parameters directly.

2. THREE PHASE CIRCUITS: (4 Wires System)
(a) Balanced Loads
:Measure as in '1' above in any of the phase. Total power is the value measured multiplied by 3 (For Clip on Wattmeter) & Power factor is the value measured multiplied by 1 (For Clip-on P.F Meter).
(b) Unbalanced Loads Measure as in '1' above in each of the three phases. Total power of the system is the sum of the power measured in each of the three phase (For Clip-on Wattmeter).
Power factor is the algebraic mean of the individual readings of the three phases (For Clip-on PF. Meter)

3. THREE PHASE CIRCUITS: (3 Wires Systems)
Derive a Neutral with the help of a Neutral Box and measure as in '2' above.
