HIOKI CLAMP ON POWER HiTESTER 3286-20

HIOKI CLAMP ON POWER HiTESTER 3286-20

Functionality and Safety Packed into a Handheld Unit

Single phase 600 kW & up to 20th Harmonic levels measurement Active/ reactive/ apparent power, Power factor, Phase detection, Frequency, Harmonic waveform value, or Waveform peak value Simple checking of three-phase lines (Should be balanced and no distortion)

Note: The 3286-20's three-phase power measurement method calculates and displays the power values for a sine wave input at 50/60 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).

Basic specifications (Accuracy guaranteed for 1 year, or opening and closing of the clamp sensor 10,000 times)
