Manual Capacitance & Tan-Delta Tester


PE-HVTD-12/100 is a manually operated capacitance & tan-delta test system with inbuilt 12 kV AC power source measurement bridge and a reference SF6 gas filled standard capacitor.

The compact design of the system uses the principle of three winding differential transformer on a high permeability mu-metal core to measure the capacitance & tan-delta of the object accurately. The system is provided with high voltage protection devices, and contained in a sturdy metallic housing with mu-metal lining which shields it from external electromagnetic & electrostatic influences. Built-in battery powered null indicator makes the system suitable for operation in workshop, factories, high voltage switch yards etc. It is suitable for both grounded as well as ungrounded objects.

The instrument is calibrated in our NABL accredited test laboratory which delivers results traceable to national standards.
