XD58 Wireless Synchronized Testing System for Transformer Station Commissioning Procedures

XD58 Wireless Synchronized Testing System for Transformer Station Commissioning Procedures

The XD58 system is an innovative solution that overhauls the commissioning/start-up procedures of transformer stations. The system achieves distributed, all wireless, and fully synchronized control and testing for the whole commissioning procedure with advanced wireless communication capability and wireless synchronized triggering mechanism. The system provides breakthroughs on the extensiveness, effectiveness, and efficiency for the commissioning procedures, when compared with conventional instruments and procedures.

Complying Standards

•  GB 50150-2006 Standard for hand-over test of electrical equipment for installation of electrical installations.

•  GB/T 24842-2018 Overvoltage and insulation coordination of 1000kV UHV AC transmission project.

•  GB/T 50064-2014 Code for design of overvoltage protection and insulation coordination for AC electrical installations.

•  DL/T 620-1997 Overvoltage protection and insulation coordination for AC electrical installations.

•  DL/T 782-2001 Code of start-up & completion acceptance for power transmission & distribution project of 110kV and above.

Key Features

•  Go wireless:With 3G/4G cellular and Wi-Fi capabilities, there is no more setting-up of long wires and cables, only close-up installations of sensing units are needed.

•  Highly efficient:The system coordinates the operations of each testing unit; all test items are completed with one click and one cycle of circuit breakers.

•  Highly reliable:All testing channels can be triggered individually or synchronized; different triggering modes validate each other to ensure a reliable triggering.

•  Highly accurate:Localized sensing unit installed close to the subject being tested minimizes signal deformations.The testing system have low background noise and high interference resistance.

•  Physically robust:All testing units are IP65 rated.Sensors have open-circuit protection to ensure reliable grounding of the electrical installations.
