AC Hi-Pot Testing
Venturetronics’ High-Voltage Lab utilizes the state-of-the-art Hipotronics 100 kV, 100HVT system for AC Hi-Pot Testing. This cutting-edge system is designed to perform over-voltage or high-potential tests, commonly known as Hi-Pot tests. These tests are vital to ensure that the Device Under Test (DUT) insulation possesses a minimum level of dielectric strength required to withstand in-service electrical stresses. The principle behind AC Hi-Pot Testing lies in subjecting the insulation to a higher voltage for a brief period (typically 1 minute), demonstrating its ability to withstand such stresses, thus minimizing the risk of in-service failures.
The Hipotronics 100 kV, 100HVT system is versatile and can be effectively used to test a wide range of objects, including transformers, power cables, bushings, capacitors, and various other electrical insulating materials.

DC Hi-Pot Testing
Our lab employs the advanced Megger 15 kV, MIT-1525 system for DC Hi-Pot Testing. This compact and versatile tester is CAT IV-rated and is specifically designed for diagnostic testing and maintenance of high-voltage electrical equipment. In addition to measuring insulation resistance up to 30 TΩ, the MIT1525 system offers various diagnostic tests, including polarization index, dielectric absorption ratio, step voltage, dielectric discharge, and ramp testing.

Lightning Impulse Testing
Venturetronics’ Lab is equipped with the capability to perform lightning impulse testing up to 30 kV using Prima’s SUG61005TBX system. Impulse voltage test systems are crucial in testing transformers, cables, gas-insulated switchgear (GIS), insulators, arresters, and other high-voltage devices. These systems generate lightning impulse voltage (LI, 1.2/50 μs), chopping lightning impulse voltages (LIC, front time 1.2 μs, front, crest, or tail chopped), and switching impulse voltage (SI, 250/2500 μs) in accordance with relevant international standards.
