Transformer PD Detecting and Positioning System

Core standards

• GB/T 7354-2003 Partial discharge measurtments (IEC60270：2000 IDT)
• Q/GDW 11063-2013 Technical specification for ultrasonic partial discharge detector
• Q/GDW 11304.5-2015 Technical specification for energized test device of electrical equipment Part5:Technical specification for high-frequency partial discharge detector

Features

• High accuracy

     The instrument uses pulse current, ultrasonic, high frequency, ultra high frequency and other detection means to verify the results of the PD test, the PD detection accuracy is very high.

• High sensitivity

     The detection sensitivity is less than 0.1pC.

• Precise positioning

     The instrument uses three-dimensional modeling positioning technology, can accurately locate the PD position.

• Strong anti - jamming technology
  The instrument's design is the use of spectrum analysis, frequency filtering, signal separation and other technical means, can effectively filter out the interference signal.
• Strong diagnostic and analysis capabilities

     There is a big data base in our system. It has the typical curves for different kinds of defects. The history records are saved in system. It’s easy to find the potential problems per comparing with the records.

• Wireless

     Every unit is wireless and working per battery. So it’s easy to install it in different positions. It saves a lot of works and costs.

• Distributed placement

     The sensor and the detection unit can be arranged at each detection position of the transformer.

• Good compatibility

     Support the transformer built-in sensors and third-party testing equipments access to our instruments.

• Easy installation

     Detection unit, the sensor can be fixed on the transformer to the magnet, strap, buckle, etc., on-site installation is convenient.

• Wide applicability

     The instrument is suitable for all kinds of high voltage test power supply.
