Loop testers are used to ensure that protective devices (fuses, circuit breakers etc) operate effectively proving that in a real electrical fault situation that protection devices operate correctly ensuring power is removed from the circuit quickly making for a no harm situation. Sonel have a full range of short circuit loop impedance meters designed not to trip RCDs from standalone loop testers to loop testers combined with additional test functions and multifunction instruments that combine all necessary testers into one unit.
Measurements of impedance in a short circuit loop. L-PE circuit, L-N, L-L circuit, L-PE(RCD) circuit – without tripping the circuit breaker ≥ 30 mA. Low voltage resistance measurement: continuity measurement – DC current +200 mA with wire resistivity reset low current resistance measurement with accoustic signalling, the measurements are posible in instalations 220/380 V, 230/400...
MPI-530 meter is a multi-functional instrument for electric shock protection measurements including the option of various methods for measuring earthing and earthing resistance. Additionally the meter enables its user to analyse power supply parameters, records and displays them on its screen. The instrument automatically measures the insulation resistance in a socket and in 3 -,...
The MPI-520 multifunction meter is dedicated to perform diagnosis of electrical installation according to IEC 61557 standards. Digital meter MPI-520 is designed to measure impedance of a short cicuit loop also without triggering RCD, parameters of RCD, insulation resistance, earthing resistance, continuity and also for phase sequence testing. Furthermore to measure and logging of AC...
