The HT7052 is a versatile battery/mains controlled test instrument used for the testing of protection safety. It utilizes high test voltages of up to 10kv. It is a high voltage protection analyzer with included diagnostic apparatus, for example, Polarization Index (PI), Dielectric Absorption Ratio (DAR) and Dielectric Discharge (DD). HT7052 is exceptionally appropriate for force transformers, and for measuring transducers in conveyance systems, testing protection safety of pivoting apparatus and links, generation line intermittent testing and support, and troubleshooting and investigating different types of protection issues, and so forth. Due to its strength it is best suited for use in natural operations. The operation is direct and clear to enable the user to work the instrument without the requirement for special training.
