Positron equipment test for the diagnosis of insulators under voltage

On March 14, 2019 at Izolyator plant functional tests of the Canadian company Positron Inc. tester were carried out. Tester purpose is the diagnosis of insulators under voltage.

Positron Inc. is a holding and operating company that develops and manufactures telecommunications equipment for high reliability, critical service applications. Positron develops and manufactures high voltage isolation products to protect telecommunications circuits entering substations, power generating plants and any high voltage area that is susceptible to the effects of Ground Potential Rise (GPR). The Positron Insulator Testers are revolutionary, easy-to-use lightweight tools that record defects and reveal dangerous conditions on energized suspension insulators, station posts, bushings, and lightning arresters. The E-field Testers can be used on all types of insulators (Porcelain, Composite, Glass* for contamination assessment, etc.) and are safe, easy-to-use simple and produce inherently accurate results. The company is headquartered in Quebec, Canada.

The tests were part of a set of measures for the certification of Positron testers for compliance with the technical requirements of Rosseti PJSC.

In the tests participated: development engineer of Positron Inc., Representatives of the company "Electrical solutions" — the official dealer of Positron Inc. in Russia, certification committee of PJSC ROSSETI.

The certification committee of PJSC ROSSETI includes representatives of the Equipment Test Department of the Federal Testing Center, the Interregional Distribution Grid Company of Urals, the Diagnostics Department of the Main power system of the Centre and the Scientific and Technical Center Electroengineering, Diagnostics and Service.

Testing was preceded by a presentation of Izolyator products with a description of the construction of high-voltage bushings, which was conducted by Vladimir Ustinov, Deputy Quality Director.
