Favorable results of operation of the Transec unit at JSC Petrostal Metallurgical Plant

09.03.2020

In August 2019, the Transec unit was in service in the subsidiary company of JSC Kirovsky Zavod. A short time ago, we have received an official letter with a recommendation to use our equipment.

The insulation drying process was performed on the transformer UTMRU 3500/35 in the period of August 21 to 23, 2019. The transformer was running for the entire period of service to provide the power supply to a rolling mill. The efficiency of the Transec unit was confirmed by a humidity monitoring system installed on the transformer and also by the transformer oil testing which has demonstrated a reduction in the oil humidity from 37 to 17 g/T. The dielectric properties of the oil were also improved. With regard to its physical and chemical parameters, it has achieved a full compliance with the requirements of the RD 34.45-51.300-97. The company representatives point out safety and reliability of the unit operation: the insulation drying process was performed continuously and unattended on the running transformer; no oil leakages occurred; the system tightness was confirmed by an absence of actuations of the gas protection. 

The equipment characteristics have achieved the rated values within a short time without a stoppage in production of the plant. M.Y. Geremey, Chief Engineer of Petrostal Metallurgical Plant, recommended using the Transec units at other enterprises of the JSC: "in view of the favorable experience in operation of the Transec unit at Petrostal Metallurgical Plant, I consider it possible to recommend using this equipment for continuous insulation drying of oil-filled filters at other facilities of JSC Kirovsky Zavod".

Vietnam Ha Giang Power Company will test Streamer innovative devices of lightning protection.

Ha Giang is a mountainous province with a complex topography and experiences extremely high lightning density during the thunderstorm season. 110 kV lines in the province mostly pass through mountainous terrain, many rivers, and streams, so breaks of the line wires due to lightning, are not uncommon. Most of the problem areas are concentrated in areas such as the Nam Ngan hydroelectric power plant and the city of Viet Kuang. Installation of innovative lightning protection devices to provide the region with uninterrupted power supply was necessary.
