SONEL INSULATION TESTER
It is a multifunctional meter designed for comprehensive measurements of electrical installation parameters (fault loop impedance - also in installations equipped with RCDs, earth resistance, all RCD parameters, insulation resistance, low-voltage measurement of low resistance), recording of alternating voltage, current, power, and phase sequence checking. The equipment is fully functional - visually checked - in perfect condition - as shown in the photos I sell with visible equipment (to the basic version I added a free 32A adapter for testing force sockets, batteries + charger, software for creating PE3 measurement protocols) Basic information: - Parameter measurements short-circuit loop impedance measurement with a current of 23 A at 230 V, 44 A at 440 V (Rzw = 10 Ω) possibility of measurement in the phase-phase short-circuit circuit, phase-protection circuit, phase-zero circuit automatic calculation of the short-circuit current; distinguishing between phase and phase-to-phase voltage measurements in networks with rated voltages: 115 V / 200 V and 230 V / 400 V with frequencies 45..65 Hz (measuring voltage range: 100..440 V) short circuit loop impedance measurement with 15 mA current with resolution up to 0.01 Ω, in installations protected by RCDs - Testing of AC, A and B residual current devices: automatic measurement of the complete set of circuit breaker parameters (after pressing the start button once, the meter performs the entire set measurement cycle) waveform of the forced leakage current selected by the user: sinusoidal (starting from a rising or falling edge), unidirectional pulsating (positive or negative),
