An Upcoming World Class Testing Facility

 

 

 

Background

Power sector in India is experiencing phenomenal growth. The Installed generation capacity of about 200,000 MW is planned by the year 2012  and the same is projected to increase to 6, 85,000 MW by the year 2027. This calls for putting in place necessary transmission and distribution infrastructure so that the power can reach to the bulk consumers efficiently. The projected growth in the manufacturing of all electrical equipment is around 20-30% in coming years.

Reliable and quality power to the utilities and ultimately to the end users has been a very challenging task for the generation, transmission and distribution authorities. The power from the generators to the ultimate consumers comes through lot of electrical equipment like Transformers, Circuit breakers, isolators, CTs, PTs, CVTs, Bus ducts, Reactors, GIS and other switching equipment. The reliability and quality of power depends upon the healthiness of these equipment. If any equipment in the chain breaks down, the supply gets affected. Failure of equipment during short circuit has been one of the major impediments in achieving uninterrupted supply. This calls for rigorous testing of all these equipment for their operation under short circuit conditions.

  • Need for Such Laboratory

At present the existing test facilities available in India can handle short circuit testing of transformers up to 90 MVA. Due to the lack of short circuit testing facilities, the large power transformers specially 100 MVA and above are being sent to overseas testing labs such as KEMA Netherland, CESI Italy etc. This, besides incurring huge cost on transportation and testing the equipment overseas, causes delay in commissioning of projects to the tune of 6-9 months.

On the initiative of Ministry of Power, Govt of India, National High Power Test Laboratory Pvt. Ltd. (NHPTL), a Joint Venture Company of NTPC, NHPC, POWERGRID, DVC and CPRI has been incorporated for the establishment of a fully independent, stand alone, state of the art, professionally managed, international class, On Line High Power Short Circuit Test Facility in India, to provide a full range of short circuit testing for the national power equipment manufacturers, national power utilities and international power equipment manufacturers from SAARC, ASEAN & Middle East Countries  in conformance to Indian and International Standards. Bina Substation of POWERGRID has been found as the most suitable site for setting up the lab considering all aspects such as high fault current, availability of 400 kV & 765 kV in-feeds to the Lab, availability of other logistic supports and central location of the station providing easy access through National/State High ways and Railways. Nearest airport is at Bhopal about three hours drive from Bina.

Project Details

The project of NHPTL Test facilities comprises of Two Phases:

Phase-I

This consists of High Voltage Transformer Testing (HVTR) Lab to test the large power transformers of 132kV, 220 kV, 400 kV & 765 kV class  and another Medium Voltage Transformer Testing (MVTR Lab) lab to test the transformers of 11kV to 66 kV Class. Phase-I is expected to be commissioned shortly in FY 2016-17.

Phase-II

This consists of High Power Synthetic (HPS) lab for short circuit testing of Switchgears (Circuit Breakers) up to 550kV, 63 kA for Short-Circuits duties with synthetic methods and High Current low Voltage (HCLV) lab for testing high current withstand capability of electrical equipment such as LV Bus Bar, LV Contacts, LV breakers, LV Dis-connectors, LV switchgear, Bushings, CT, up to 400 kA rms with 1100 kA peak.

Stage-III & Stage-IV together

(as defined in the Feasibility Report) have been envisaged as phase-II of the project. After completion of Phase-I, the execution of Phase-II is proposed to be taken up.
