Sonel MPI-505: Multifunction Electrical Installations Meter

Description

Measurement of short-circuit loop parameters:

• in L-PE, L-N, L-L circuits as well as in L-PE (RCD) circuits – without tripping RCD breakers of current 30 mA.
• impedance measurement of short-circuit loops in power networks of nominal voltages: 115/200 V, 220/380 V, 230/400 V, 240/415 V and frequencies in the range of 4565 Hz..

Testing of AC and A types residual current circuit breakers:

• testing of regular and selective residual current circuit breakers of nominal differential currents: 10 mA, 30 mA, 100 mA, 300 mA, 500 mA, 1000 mA,
• I_A trip current measurement,
• t_A trip time measurement for 0.5I_n, I_n, 2I_n, 5I_n,
• measurement of earth continuity and touch voltage without tripping RCDs,
• functionality of automatic measurement of residual current circuit breaker parameters.

Measurement of insulation resistance at voltages: 100 V, 250 V, 500 V and 1000 V.

Low-voltage measurement of resistance, protective connections and equipotential bonding:

• measurement of continuity of protective connections with current ±200 mA,
• automatic calibration of test leads – capability of using any test leads,
• measurement of resistance with low current and acoustic signaling.

Quick verification of correctness of the PE wire connection with a touch probe.

Measurement of AC voltage.

Indication of phase sequence.
