Multifunctional meter of electrical installation parameters MPI-530-IT WMPLMPI530IT

Multifunction meter MPI-530-IT of the latest generation, allowing to perform all measurements in the electrical installation in accordance with the PN-EN 61557 standard:

• short-circuit loop impedance with resolution up to 0.001 Ω – accurate measurement also in circuits with RCDs,
• parameters of RCDs, also in isolated IT networks,
• insulation resistance,
• earthing resistance ,
• continuity of protective and equipotential bonding.

The device has an innovative memory that allows saving tens of thousands of results in the structure of a ready protocol.

Data from memory can be transmitted to a PC via a USB cable or wirelessly via Bluetooth®.

Fault loop impedance measurements:

• measurement of short-circuit loop impedance with a resolution of 0.001 Ω with a current of 23 A (44 A at phase-to-phase voltage) - short-circuit resistor Rzw = 10 Ω,
• measuring voltage range: 95...440 V, frequency 45...65 Hz,
• measurement of short-circuit loop impedance with a resolution of up to 0.01 Ω, in installations protected by RCDs with IΔn ≥ 30 mA without tripping,
• automatic calculation of short-circuit current; distinguishing phase-to-phase voltage and phase-to-phase voltage,
• measurements using UNI-Schuko plug with a button that triggers the measurement (also with L and N wires swapped) or 1.2 m, 5 m, 10 m, 20 m long wires with possible use of 3-phase socket adapters. (AGT),
• selection of installation protections and automatic assessment of the measurement result.

Testing of AC, A, F and B RCDs:

• measurement of ordinary, short-time delay and selective circuit breakers with rated residual currents of 10, 30, 100, 300, 500 and 1000 mA,
• function of automatic measurement of a full set of circuit breaker parameters (after pressing the "START" button once, the meter performs the entire programmed cycle of measurements, including the possibility of measuring the impedance of the L-PE short-circuit loop with a current of 15 mA),
• user-selectable shape of the forced leakage current waveform: sinusoidal (starting from the rising edge or (positive or negative), unidirectional pulsating (positive or negative), unidirectional pulsating with DC bias (positive and negative), constant (positive and negative),
• measurement of IA trigger current with increasing current,
• measurement of tripping time tA at currents ½IΔn, 1IΔn, 2IΔn and 5IΔn ,
• measurement of touch voltage UB and protective conductor resistance RE without tripping the circuit breaker,
• detection of L and N wires inversion in the socket ; does not affect the performance of measurements,
• possibility to measure tripping current IA and real tripping time tAI with one RCD trip,
• measurements for voltage 95...270 V.
