COMBI 521 HT Instruments Insulation

COMBI521 Multifunction tester for electrical installation safety tests, power quality analysis and EVSE safety tests

Features:

• COMBI521 carries out tests on electric systems in compliance with IEC/EN 61557-1 and therefore measurements of continuity of the protection cable, insulation resistance (with calculation of PI and DAR), overall earth resistance, RCDs type B, A and AC tripping time and current, line / fault impedance with calculation of prospective short circuit / fault current, phase sequence and conformity. COMBI521 also allows measuring and saving environmental parameters (illuminance, temperature), leakage current and electric quantities such as voltage, current, power factor, power and harmonics on single-phase systems.
• In combination with EV-TEST100, COMBI521 performs verification and control of electric car charging stations (EVSE) in accordance with IEC / EN 61851-1 and IEC / EN60364-7-722 standards
• The instrument is provided with the innovative AUTO function: by selecting this function and only setting the value of RCD current, COMBI521 carries out tests of overall earth resistance, RCD tripping time and insulation resistance in a sequence. At the end of the test, the device shows all results with the indication of compliance or non-compliance with the standards with simple symbols OK or NOT OK.
• The internal memory allows saving the measures and subsequently transfer them onto the PC through the optical/USB connection. Thanks to the brand new HTAnalysis App, free to download for iOS and Android systems, COMBI521 is capable of transferring measured and recorded data onto tablets and smartphones, thus giving the operator the possibility to customize and share through HtCloud the result of their tests.
