PDStar is the ideal tool 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. Infrared Technology has been applied with PD technology together by PDStar.
The PDetector is an ideal device for On-Line Partial Discharge (OLPD) testing of MV and HV equipment which employs all 5 types of OLPD sensor technology: Ultra-High Frequency (UHF), Acoustic Emissions (AE), Ultrasonic, High Frequency Current Transformer (HFCT), and Transient Earth Voltage (TEV). The information from multiple sensors gives the PDetector the versatility to detect all types of PD in all types of substation apparatus. The exact type of PD activity can be determined effectively using multiple on-screen data spectrum analysis. The PDetector greatly simplifies and standardizes the routine OLPD testing procedure by using the intelligent patrol function, the App, and the PMDTCloud. It is a very powerful and helpful tool for substation operators to conduct routine testing in a substation quickly, to determine what the issue is, and where it is located.
Portable Online Partial Discharge Diagnostic and Location System
The PDiagnostic is a portable system that utilizes Ultra-High Frequency (UHF), Acoustic Emissions (AE), High-Frequency Current Transformer (HFCT), and Transient Earth Voltage (TEV) sensors to detect, analyze, and locate the PD signals in real time for a multitude of medium and high voltage electric power equipment.
The multi-channel PDiagnostic system locates PD on power equipment down to the measurement of a meter by utilizing Acoustic-Electromagnetic Combination Location Technique, Time Difference of Sig nals' Arrival (TDOA), Partial Discharge Signals Separation (PDSS), and 3D Positioning Technology with PC software included.
The system features advanced PD diagnostic, automatic PD type pattern recognition, and accurate PD Location capabilities. The PDiagnostic is an ideal trouble-shooting tool for your PD programs. Severity is determined and maintenance suggestions are provided accordingly.
