W. S. Test Systems Private Limited (WSTS) was established during 1984 at Bangalore as a joint venture between W. S. Industries (India) Limited, Chennai and MWB Messwandler-BauAG, Germany, with the objective of making available high voltage test and measuring equipment of International Standards at competitive prices to various segment of users in India and Abroad. The company has established itself as a leading manufacturer of High Voltage Test and measuring equipment in India. It is currently engaged in the production of high voltage construction kits and related instrumentation - popular among research / training institutions and medium voltage power equipment manufacturers all over the world.
Besides manufacturing the multifunctional AC/DC/Impulse High Voltage construction kit up to 420kV, the company acquired the technology from Passoni & Villa , Italy and now manufactures special high voltage AC cascade transformers (up to 800kV), PD free Coupling/Measuring Capacitors (up to 1200kV), SF6 Standard Capacitors (up to 400kV), Impulse Voltage Generators (up to 3000kV), Impulse Current Generators (up to 150kA), HVDC test sets (up to 1200kV) and Measuring Sphere-gaps (up to 1000mm dia.) strictly conforming to the relevant IEC Standards
From the beginning, WSTS has been actively engaged in evolving new design for test equipment to cater to the specific customer requirements for their testing needs from Medium Voltage up to UHV system voltages
