Within the investment program IDGC of Centre — Smolenskenergo division received eight electrical laboratories in excess of 46 million rubles for the diagnostics of electrical equipment of substations and locating faults in cable lines.
The cars, which the laboratories are mounted on, have good cross-country ability, which allows for diagnostics of hard-to-reach facilities.
Electrotechnical Laboratories (ETL), based on GAZ 33081 and GAZ 27057, are designed to: test transformer and distribution substations of
The acquired combined laboratories ELA 10T-3 and 10T-1 based on GAZ 33081 can simultaneously determine the fault location of paper-oil insulated cable lines of 0.4 — 10 kV and test distribution and transformer substations of
All high voltage sources in the system are controlled by the excess of the permissible level of voltage: when the level reaches 110% of nominal it is automatically disconnected. The system is powered through a distribution transformer, and the 220V mains control provides a system stop in the case of too much voltage deviation. It is also possible to lock the system with an external safety device with a lamp indicator and a lock switch.
In 2013, under the investment program it is planned to purchase a modern laboratory, which will perform tests and fault location of cable lines with XLPE insulation.
