HT7051 is a professional insulation tester with a programmable test voltage up to 5 kV. HT7051 is designed for measuring insulation resistance with a programmable test voltage up to 5 kV DC and a measurement range up to 10 MΩ, making it highly useful in various industrial applications (testing electric machines, power transformers, electrical cables, switchgear, universal devices, etc.) within BT standards. The device allows testing in FIX (fixed test voltage), ADJUST (programmable test voltage), and RAMP (programmable test voltage and application time with a choice of one of 3 ramp types) modes, suitable for any situation. Measurements of parameters such as Polarization Index (PI) and Dissipation Factor (DAR) are extended tests to assess insulation quality. HT7051 comes with a NiMH rechargeable battery with an integrated charger, providing impressive measurement duration. It features internal memory for storing measurements and can be connected to a PC for data transfer. All components are housed in a durable, portable case, ensuring safe and reliable on-site use.
