WHY UHF?
UHF PD detection method can be used for a wide rage of high voltage equipment including CIS, GIB, AIB, Transformer, etc.
UHF PD detection method can detect PDs earlier than other methods.
UHF PD detection method can diagnose causes of defect in real time more accurately
PD Sensors for GIS and AIS, Noise Gating Sensors, UHF Drain Valve Sensor for Transformer
-
Superior accuracy and noise gating features based on the state-of-the-art UHF technology. Conventional PDMS systems may convert PD signals in UHF band to RF band because their systems do not have performance enough to analyze PD signals in UHF band directly. PDMS systems of APM Technologies include high performance data acquisition units that are enabled to analyze PD signals in UHF band without down converting.

APM 7000 & APM 7000p
APM7000 is the most effective insulation diagnosis system that analyzes the cable’s failure phenomenon due top artial discharge in real time to prevent accidental power failure.
-
Localized defects of insulation system cause Partial Discharge. Electric trees which is made by Partial Discharge can lead to insulation breakdown.
Partial Discharge measurement is useful method to decide how much systems are degraded by electrical and thermal stress, manufacturing defects and installation errors in cable insulation system.
APM7000P is designed as compact size for portable PD measurement and enabled to operate for continuous monitoring without computer. This equipment aims at preventing electrical accidents of cable through identifying insulator faults in advance.
