XD50WS PD Detection & Localization System for Switchgears

XD50WS PD Detection & Localization System for Switchgears

Designed specifically for partial discharge (PD) detection and localization on switchgears (cabinets). The system integrates acoustic (AE), TEV, and UHF methods to preform synchronized PD detection and localization.

Complying Standards:

•  DL/T* 417-2006 Guide for partial discharge measuring of power equipment.

•  Q/GDW** 11061-2013 Technical specification for ultrasonic partial discharge detector.

•  Q/GDW 11063-2013 Technical specification for transient earth voltage partial discharge detector.

•  *DL/T stands for “Recommended standards of electric power industry of China”.

•  **Q/GDW stands for “Corporation standard of State Grid Corporation of China”.

Key Features:

•  Highly Accurate:Testing measures including AE, TEV, and UHF are combined and cross validated with each other to achieve a high accuracy.
•  Industry-leading sensitivity:Sensitivity equal to or better than 0.1pC.
•  Robust to interference:Complete suite of interference reducing technologies: Spectrum analysis, frequency-selective filtering, interference separation, and comprehensive shielding.
•  Multi-use:Can be used for off-line testing, on-line surveying, and even on-line monitoring.
•  Diagnosis and analysis:Full range of analysis assisting graphical interfaces: PR, PRPD, PRPS, Correlation, and Selecting/masking windowing.Built-in interference and discharge patterns for automated signal classification.
•  Synchronization:Wired or wireless synchronization of timing and phase.
•   Accurate localization:Supports highly accurate electric, acoustic, and electric-acoustic localization.
•  Go Wireless:Multiple detector units working together with wireless communication and synchronization.Adding or removing detector units as needed.
•  Easy to install:Detector units and sensors can be easily installed with magnets.
•  Power supply compatibility:Compatible with a wide range of HV-testing power supplies.

Technical Specifications:
