Instrument transformers convert the currents and voltages of the H.V. lines to values, which are measurable by meters and protections. IGS offers a wide range that covers all our customers' needs. Current, voltage and combined transformers, oil-paper or gas insulated up to 800 kV.
We are offering a wide range of reliable and energy efficient disconnectors to meet the requirements of different sites and network conditions. The disconnectors range from 72.5 kV to 550 kV. The disconnectors are designed as per IEC 62271-102 and IEC 62271-1 standards. Also other standards and regulations (eg, IEEE, GOST, and GB) can be met on request. Accredited testing laboratories carry out type tests on the disconnectors in accordance with the latest regulations. World-class quality of dis
The surge arresters are the primary protection against atmospheric and switching over voltages. We are offering a complete range of surge arresters for high and medium voltage applications. The range comprises of AC and DC solutions up to 1,100kV and arresters for special applications like railways, DC-voltage limiting devices and many other purposes. The designs comply with the IEC 60099-4 and ANSI/IEEEC62.11.
