Thiết bị kiểm tra lắp đặt điện đa chức năng Sonel MPI-530
Measurement of short circuit loop impedance:
- impedance measurement with resolution 0,001 Ω and 23 A current (44 A phase-to-phase) - short-circuit resistor RZW = 10 Ω,
- measurement range: 95...440 V, frequency 45...65 Hz,
- measurement of short circuit loop impedance with resolution 0,01 Ω, in protected systems without tripping the RCD’s with IΔn ≥ 30 mA,
- automatic calculation of short-circuit current, differentiating between phase-to-phase and phase-to-neutral voltage,
- measurements using UNI-Schuko plug with measurement triggering button (also when L and N leads are exchangeable) or 1,2 m, 5 m, 10 m, 20 m test leads, with optional use of 3-phase socket adapters (AGT),
- selection of installation protections and automatic evaluation of measurements results.
Tests of residual current devices (RCD), types AC, A, F, B and B+:
- measurement of general, short-time delay and selective RCD’s with rated residual current of 10, 30, 100, 300, 500 And 1000 mA,
- automatic measurement of all RCD parameters (when the START button is pressed, the meter performs the whole measurement cycle, including the.
L-PE short circuit loop impedance measurement with 15 mA current),
- user selected waveform of forced leakage current: sinusoidal (start from increasing or decreasing edge), unidirectional pulsating (positive or negative), unidirectional pulsating with DC bias (positive and negative), direct (positive and negative),
- measurement of tripping current IA using the ramp current,
- measurement of tripping time tA at ½IΔn, 1IΔn, 2IΔn and 5IΔn ,
- measurement of touch voltage UB and protective conductor resistance RE without the RCD tripping,
- detection that L and N conductors are switched in the socket; will not affect the measurement,
- measurement of tripping current IA and actual tripping time tAI at single activation of RCD,
- measurement for 95...270 V voltage.
Insulation resistance measurements:
- test voltage values: 50 V, 100 V, 250 V, 500 V and 1000 V,
- insulation resistance measurements up to 10 GΩ,
- in-socket measurements using the UNI-Schuko adapter,
- meter is protected against voltage on the tested object and voltage appearing during the measurement,
- auto-discharge of the object after the measurement,
- automatic measurement of all resistance combinations in three-, four- and five core leads using the additional AutoISO-1000C adapter,
- acoustic signalling of five-second periods to enable determining the time profile during the insulation resistance measurements.
