10K-PI Insulation Diagnostic Tester
10K PI is an Insulation Diagnostic Tester having test voltage range up to 10KV, designed & developed indigenously at the state of the art R&D laboratory to conduct automatic insulation tests on high voltage equipment’s like Transformers, Cables, Bushings, Switchgears & Rotating Machines.
10K PI comes in two ranges of short circuit current of 3mA and 6mA. 10K PI is a microprocessor based instrument deploying the latest technology & very high speed data sampling to give correct, repetitive readings & quality performance under harsh electrical conditions. It has a wide insulation resistance range up to 50TΩ.
- There manually selectable convince DC ranges for application
- Cable and cable sheath testing up to 12 kV between metallic sheath / armoured and mass of earth.
- Automatic sheath fault pre-location with high precision measuring bridge method.
- Cable sheath fault pin pointing by pool of potential method.
- Automatic discharging facility of cable under test, in case of power failure or after switching off.
- Conversion of high-resistance faults in low-voltage cables.
- Burn mode for conditioning the sheath fault.
- It is extremely user friendly in obtaining the fault distance; it uses a micro-controller based fault distance calculator that enables the operator to get the pre-location measurements with precise accuracy.
- Continues operation for extended period in case of pin-point difficult sheath faults.
- Rugged construction and easy to carry on site.
