10K-PI is an insulation diagnostic tester with a test voltage range of up to 10KV. It is designed and developed indigenously at our state-of-the-art R&D laboratory to conduct automatic insulation tests on high voltage equipment like transformers, cables, bushings, switchgear & rotating machines.
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. 10KPI 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.
Model 10K PI is mains and battery operated portable & compact insulation tester for outdoor
applications. The battery backup of 8 Hours makes it suitable for field operations. IP 65 rating keeps 10K PI safe from water & dust ingress. It complies with CAT IV 600V for safe operation. The instruments & its accessories are certified as per relevant IS/IEC standard.
The Information displayed on the large backlit LCD includes insulation resistance, leakage current, capacitance, battery status & timer. Three programmable timers are provided to conduct various tests like Polarization Index (PI), Dielectric Absorption Ratio (DAR), Dielectric Discharge (DD), Step Voltage (SV), Breakdown Voltage (BDV), and Burn Test. 10K PI can store up to 1000 test results. PC interface via USB & RS-232 for data transfer. The PC software for report generation & data trending analysis helps to keep records of capital equipment. The instrument has the automatic discharge facility for capacitive load discharge at the end of the test.

Applications
The Insulation Resistance Test is an essential test that helps to verify the condition of electrical
insulation. Insulation resistance quality of an electrical system degrades with time, environment
condition i.e. temperature, humidity, moisture and dust particles. The instrument is designed for
routine insulation resistance testing and diagnostic testing like PI, DD, DAR, SV, BDV & Burn test of
high voltage electric apparatus like transformers, generators, motors, cables, bushings, LAs,
switchgear, etc. and is temperature independent. Trending of data can reveal vital information
about insulation quality and enables the user to take informed decision.
