Products Description
The HMPD-9104 Partial Discharge Tester is a specialized instrument designed to measure and analyze the insulation performance of electrical equipment. This system employs advanced electronic and computer integration technology to perform signal amplification (analog, electronic, and digital), filtering, data acquisition, data processing, graphical display, and automatic test report generation, thereby enabling the measurement of partial discharges and fault diagnosis.
