CableEye M3U HVX high-voltage module

Cami Research has introduced a high-voltage module for its CableEye M3U cable test system that permits expanded testing for insulation resistance and dielectric breakdown.

After checking for opens, shorts, miswires and resistance limits, the HVX hipot module will apply a user-selectable voltage from 10 to 1500 DC, or 10 to 1000 RMS AC, to each connection group in the cable.

Current leakage detected during the high-voltage test phase provides a measure of insulation resistance up to 1 G Ω, and any leakage current exceeding a preset limit reveals the presence of moisture, flux or other contamination on exposed contacts.

The test capability allows users to meet the industry-standard A620 guidelines for cable and wire harness testing.

The system also produces archival-quality reports for each cable tested showing the test voltage, leakage current and insulation resistance for each wire group, and clearly denotes pass or fail.

Operator safety measures include: each login name must have system administrator authorisation to permit enabling of the high-voltage function; once logged in, the operator must confirm awareness of the presence of high voltage by pressing a hardware-enable button for that test session; during testing, a bright red light bar turns on when high voltage is present; remote test and stop switches are available; and finally, test current that exceeds 1.5 mA causes an automatic halt of that test and cessation of voltage.
