Online Insulation Testing - PD Testing for Substations PDetector is the ideal partner for condition-based maintenance programs. Online partial discharge testing is a method of inspecting the insulation of electric power systems while equipment remains energized and in service. PDetector incorporates all 5 types of online PD sensor technology. Information from multiple sensors gives PDetector the versatility to detect all types of PD in all types of substation apparatus. Furthermore, the exact type of PD activity can be determined using PRPS: void, corona, surface, particle, or floating electrode. Applications: Power Cables Transformers GIS Switchgear Substation Apparatus Sensor Technology : Detection Bandwidth Electromagnetic (EM) TEV - Transient Earth Voltage (built-in to main handheld unit) 3MHz - 100MHz UHF - Ultra High Frequency - 300MHz - 1.5GHz HFCT - High Frequency Current Transformer 500kHz - 50MHz Acoustic Sensors (AE) Acoustic Contact - 20kHz- 300kHz Airborne Ultrasonic - 40kHz Phase Resolved Partial Discharge (PRPD) - PD activity produces both electromagnetic and acoustic emissions. PRPD mode will automati********* oming signals to the power frequency 60Hz (or 50Hz). This gives the user the ability to instantly determine if PD is present.
