Product Profile of Relay Testing Unit

Ashida electronics pvt. Ltd. Developer, designers & constructors of electrical power protection relays & scada systems. The company has obtained iso 9001:2000 certifications from m/s. Bvqi, u.K. Ashida electronics pvt. Ltd offers ashida relay testing unit artuvfs unit is specially designed to suit relay testing requirements of power station testing engineers. The unit is given in portable case. The advantages of modern high tech., stability and accuracy of digital indication are in-built. Numbers of functional units are included in single cabinet. They can be used individual or in association with other unit. The artuvfs is a complete relay testing unit for testing of traction tss relays. It has got all necessary functions for relay testing viz. Auxiliary power supply, variable current source up to 100a, variable voltage source, time interval meter up to 1ms resolution etc. After adding optional phase shifter and phase angle unit, artuvfs can be used to test distance protection, direction protection relays also. The connection terminals are front loaded and plug in or wire connections can be used. The key features of the ashida relay testing unit
