Insulating Oil Dielectric Loss & Resistivity Tester

The HZJD-2Z Insulating Oil Dielectric Loss and Resistivity Tester measures the dielectric dissipation factor (tanδ), relative permittivity and DC resistivity of insulating oil, transformer oil and other insulating liquids quickly and accurately. Built to the leading international standards for liquidinsulating materials, it integrates the test cell, temperature controller and sensor, dielectric-loss bridge, AC test source, SF₆ standard capacitor, high-resistance meter and DC high-voltage source into a single instrument. Full digital, fully automatic measurement is driven from an 800×480 full-touch colour display with a guided menu, so any operator — without specialised training — can obtain repeatable, storable and printable results. It is the right choice for power transformers and critical assets, substations, transmission & generation facilities, oil laboratories and acceptance / maintenance testing
