Product Specification:

A relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal.

Linear Enterprises has the experienced field engineers and state of the art equipment to set/program, test and calibrate all makes and styles of protective relays, indicating meters and energy meters, Simplex type panels, Duplex type panels, Control desks etc.

We offer services related to protection relays viz settings, testing & calibration ( Procedure in electromagnetic relays ). The secondary Injection Test set and Primary Injection Kits upto 2500A processed by us enables us to test the relays at site by primary as well secondary injection method.

We provide maintaining of Panel Boards for Power & Control Systems and have expertise in maintaining of PCC, MCC, APFCR Panels, RTCC Panels, Marshaling Kiosks & AMF Panels.
