The KDZD3088 Ultrasonic Partial Discharge Online Diagnostic Instrument is an advanced, portable solution for live-line inspection of power systems up to 110 kV. Leveraging high-sensitivity ultrasonic sensors and intelligent signal processing, it detects and analyzes characteristic acoustic emissions from partial discharges caused by insulation defects, contamination, or mechanical issues. Designed for field use—with real-time cloud sync, GPS tagging, and mobile integration—it enables fast, accurate, and non-intrusive PD diagnostics on overhead lines, substations, and rail electrification systems.
Product Overview KDSL-S500A Three-phase Large Current Generator (hereinafter referred to as Three-phase Current Rise) is the test equipment developed by our company. It combines the advantages of similar products at home and abroad. It adopts numerical control technology and has strong anti-jamming capability. Compared with the previous generation of current rise, the converter made of low power consumption and large capacity self-coupling voltage regulator and high permeability iron core has the advantages of large output power, small size and light weight. It is mainly used for calibration of thermal relay, motor protector, contactor, breaker, air switch, switch cabinet, breaker and protection panel.
The KD2675 series AC/DC withstand voltage insulation analyzer integrates functions such as AC withstand voltage, DC withstand voltage, insulation resistance, arc detection, and open circuit detection. The overall size is 2U/half width, with a depth of 300mm. It is compact, lightweight, precise, efficient, reliable, and stable, with rich interfaces.
