Installation tester for testing protective circuity according to DIN VDE 0100, RCD type B

A wide-range measuring instrument makes it possible to use the testing device for all alternating current and three-phase supplies with voltages from 65 to 500V and frequencies from 15.4 bis 420Hz.

• Loop and line impedance measurement
• Measurement of the insulation resistance with the nominal voltage, or with a variable or rising test voltage
• Low-resistance measurement
• Earth resistance measurement
• Location isolation measurement
• Universal connection system
• Display of approved circuit breaker types for electrical installations
• Testing the start-up of energy consumption meters
• Computation of line lengths for standard cross-sections of copper conductors
• Measurement of bias, leakage and compensating currents up to 1 A as well as operating currents
• Measurement of the rotating field direction (phase sequence, maximum phase-to-phase voltage)
• Measurement of the contact voltage without tripping the circuit breaker
• (In this case, the contact voltage relative to the nominal residual current is measured with 1/3 of the nominal residual current.)
• Trip testing with nominal residual current, measurement of the tripping time 

Special testing of systems and/or RCD circuit breakers

• Testing of systems or RCD circuit breakers using a rising residual current with a display of the trip current as well as the contact voltage at the instant of tripping.
• Testing of RCD circuit breakers with: ½ × I_ΔN, 1× I_ΔN, 2× I_ΔN, 5× I_ΔN
• Testing of RCD circuit breakers that are intended for pulsating DC residual currents; testing is performed with positive or negative half-waves
• Testing of RCD circuit breakers with adjustable residual current in order to determine the contact voltage and the trip current (selective S, SRCDs, PRCDs, Schukomat, Sidos, type G/R, AC, A, A-EV, F, F-EV, B, B+, B-MI)
• Testing of the alternating current and direct current tripping of universal current sensitive RCDs (type B)

Evaluation software

• The software captures all the important data for reporting in accordance with DIN VDE 0100 Part 600
• Test reports (ZVEH) can be generated automatically
• Distribution structures with circuit/RCD data are individually definable
• Created structures can be saved and loaded into the tester if necessary
• The tester and the PC can exchange data bi-directionally via a USB connection
• Data may be exported as EXCEL, CSV and XML
• USB interfaces
• Push-print function – transmission of measured value after successful measurement
