Multi-function Electrical System Meter • MPI-540

The meter has above-average functionality. It combines the measuring capabilities of several devices, while ensuring equally good accuracy.

• MPI-540 can record 50/60 Hz power quality parameters in accordance to S class of EN 61000-4-30:

• • voltage L1, L2, L3, – average values in the range up to 500 V, » L1, L2, L3 currents, – average values, current measurement in the range up to 3 kA (depending on the current probes used),
  • frequency in the range of 40 Hz – 70 Hz,
  • active (P), reactive (Q) and apparent (S) power,
  • power factor (PF), cosφ, tanφ,
  • harmonics (up to 40th for voltage and current),
  • total harmonic distortion (THD) for current and voltage,
  • recording of events for current and voltage,
  • energy flow – 4 quadrants.

• MPI-540 can be used for all measurements for commissioning of electrical installations in accordance with applicable regulations:

• • • short circuit loop impedance (also in circuits secured with RCDs),
    • RCD parameters,
    • insulation resistance,
    • earth resistance (4 measurement methods + soil resistivity measurement),
    • continuity of protective and equipotential bondings,
    • light intensity measurement,
    • phase sequence test,
    • motor rotation direction test.
