Description

5K PI Diagnostic Insulation Tester is a high‑performance, microprocessor‑based insulation resistance tester designed for accurate insulation resistance testing and condition assessment of high‑voltage electrical equipment. It measures insulation resistance up to 50T ohm with a shot circuit current of 6mA.It is suitable for testing transformers, motors, generators, cables, switchgear, bushings, and other critical assets in industrial and utility environments. Built for reliable field performance, the instrument delivers stable, repeatable results and supports effective preventive and predictive maintenance programs.The tester performs advanced diagnostic tests such as Polarization Index (PI), Dielectric Absorption Ratio (DAR), Dielectric Discharge (DD), Step Voltage (SV), and Breakdown Voltage (BDV), enabling a detailed evaluation of insulation ageing, moisture, and contamination. It supports short‑circuit current options of 3 mA, 5 mA, and 6 mA to meet different testing standards and application needs. A large backlit LCD display ensures clear visibility of test values, while automatic capacitive discharge at the end of each test enhances operator safety and equipment protection, making it a dependable solution for professional insulation testing.
