Electronic and Control System.

Jyoti Plug-in type RE-300 & RE-400 Auxiliary Relays are widely used for interlocking functions in Thermal Power Stations, Petrochemical Complexes and Cement Plants. They are also used for multiplication of contacts, voltage selection, anti pumping in circuit breakers and as output element in PLC Systems. To protect Distribution Network, Electric Work Motors and Alternators, Jyoti has developed a wide range of Protective and Auxiliary Relays. These Relays, with solid-state technology are designed to provide primary protection to rotating electrical machinery and 11 KV-33 KV distribution feeders. They also provide back-up protection to HV transmission lines. These relays are approved by serveral consultants and are used by various electric utilities.

Jyoti has developed Microprocessor-based Temperature Scanners for monitoring temperature in HT Motors, Alternators, etc.
