MZC-306

Fault Loop Impedance Meter

Capabilities

• Fault loop impedance measurement with 0.01Ω resolution
• Low-current impedance measurement in circuits protected by RCD ≥ 30mA with 0.01 Ω resolution (100…440 V)
• Operates in networks with voltages 110/190 V, 115/200 V, 127/220 V, 220/380 V, 230/400 V, 240/415 V, 290/500 V and 400/690 V (operating range 100…750 V)
• Operating frequency 45…65 Hz
• Calculation of fault current
• Automatic differentiation between phase and phase-to-phase voltage
• Possibility of applying 1.2, 5, 10, 20 m test leads or an adapter terminated by a power network plug
• Measurement with swapped L and N conductors
• Measurement of resistance (R_S) and reactance (X_S) components

Additionally features

• Contact electrode - quick testing of proper connection of PE conductor.
• Voltage measurement 0...750 V AC (0...250 V with resolution of 0,1 V).
• Memory of 990 measurement results, ability to transfer the data to a PC via USB.
• Power supply: batteries (4 x LR14) or rechargeable batteries.

Application

This instrument is irreplaceable for all kind of electrical works, especially in situations where there is a need to check the circuits under voltage of 400/690 V. The meter is used for tests in homes, apartment blocks, public buildings, small workshops or factories and even at wind farms.

The meter is a perfect tool for testing systems, where fault currents may reach 5.3 kA (measured according to EN 61557).
