The product allows for accurate measurement of short-circuit loop impedance (resolution 0,01Ω) in L-PE circuits in networks with RCD circuit breakers. It has the function of measuring the actual actuation time and the operating current of the RCD circuit breaker with a single actuation of the circuit breaker.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eMeasurements of short-circuit loop impedance:\u003c\/b\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003emeasurement of impedance with current of 23 A (44 A at interphase voltage) - short-circuit resistor Rzw=10 Ω,\u003c\/li\u003e \u003cli\u003emeasuring voltage range: 95...440 V, frequency 45...65 Hz,\u003c\/li\u003e \u003cli\u003eshort-circuit loop impedance measurement with a resolution of up to 0,01 Ω, in installations protected by RCD circuit breakers with IΔn≥30 mA without their operation,\u003c\/li\u003e \u003cli\u003eautomatic calculation of short-circuit current; distinguishing between phase and interphase voltage,\u003c\/li\u003e \u003cli\u003emeasurements using UNI-Schuko plug with a button triggering the measurement (also with switched L and N wires) or wires with a length of 1,2 m, 5 m, 10 m, 20 m, with the possible use of 3-phase socket adapters.
