Gossen Metrawatt PROFITEST MTECH+

A broad-range measuring device allows for use of the test instrument in all alternating and 3-phase electrical systems with voltages from 65 to 500 V and frequencies of 15.4 to 420 Hz.

• Loop and line impedance measurement
• Measurement of insulation resistance using nominal voltage, with variable or rising test voltage
• Low-resistance measurement
• Earth resistance measurement
• Standing-Surface Insulation MeasurementBLUETOOTH Interface Logo
• Universal connector system
• Standard-compliant Testing of Electric Vehicle Charging Stations in accordance with IEC 60364-6 and IEC 61851

>

Testing of residual current devices (RCCBs)

• Measurement of contact voltage without tripping the RCCB
• Contact voltage is measured with reference to nominal residual current using 1/3 of the nominal residual current value
• Tripping test with nominal residual current, tripping time measurement

>

Special testing for systems and RCCBs

• Testing of equipment and RCCBs with rising residual current including indication of tripping current and contact voltage at the moment the RCCB is tripped
• Testing of RCCBs with: 1/2x, 1x, 2x, 5x IΔN
• Testing of RCCBs which are suitable for pulsating residual direct current, testing is conducted with positive or negative half-waves
• Testing of RCCBs with adjustable residual current for determining contact voltage

>

Testing for special RCDs

• Selective S, SRCDs, PRCDs (Schukomat, Sidos and others), types G/R, AC, A, F, Type B, B , EV
