UNI-T UT515B 10kV High-Voltage Insulation Resistance Tester – 10TΩ

The UNI-T UT515B is a commercial-grade, high-voltage digital insulation resistance tester. Capable of generating up to 10,000V (10kV), it measures extreme insulation resistance up to 10 Tera-Ohms (10TΩ). Featuring stepping voltage controls, automatic PI/DAR calculations, and a high-capacity 5200mAh lithium battery, it is essential for diagnosing high-voltage grid transformers and industrial substations.

Command absolute diagnostic power with the UNI-T UT515B 10kV High-Voltage Insulation Tester. When dealing with high-voltage utility grids, massive industrial transformers, and heavy-duty subterranean cables, standard 1000V testers cannot provide enough stress to expose deep insulation flaws. The UT515B is built for heavy industry in Pakistan, generating an immense test voltage of up to 10,000 Volts (10kV).

This digital megaohmmeter boasts an astronomical measurement range of up to 10 Tera-Ohms (10TΩ). It features a highly advanced Stepping Voltage function, which increases the test voltage by 10% increments to observe how the insulation reacts to gradual electrical stress. Fully equipped to calculate Dielectric Absorption Ratio (DAR) and Polarization Index (PI) automatically, it is the ultimate predictive maintenance tool for grid engineers and high-voltage contractors to prevent catastrophic electrical failures.
