CLAMP ON POWER HiTESTER 3286-20

Hioki clamp meters are best in class handheld current and voltage meters for safely and accurately measuring power lines. The 3286-20 clamp on power meter can measure voltage, current, power, power factor, phase angle, reactive power or frequency, as well as detect phase sequence on live lines at any desired point of a single-phase circuit or three-phase circuit.

CAT III 600 V

Key Features

Measure single-phase 600 kW lines and up to the 20th harmonic level
Active/ reactive/ apparent power, power factor, phase detection, frequency, harmonic waveform value, or waveform peak value
Simple checking of three-phase lines (balanced with no distortion)

Model No. (Order Code)

3286-20	Discontinued

Note: The 3286-20's three-phase power measurement method calculates and displays the power values for a sine wave input at 50 Hz/60 Hz, assuming it is balanced and there is no distortion. Accurate measurement is not possible on a three-phase line if it is not balanced, for example when controlled by an inverter or thyristor.
Since there is no integration function, it is not possible to measure total energy consumed (Wh).
