L&T offers you a wide range of Power factor Correction Relays suitable for all standard applications. Their intelligent adjustment interface ensures balanced usage of capacitors based on the number of switching operations and the connection time of each step, thus ensuring long life for switchgear and capacitors.
PGR 8800 provides effective arc flash protection using optical point and fiber sensors. The system generates a trip within 1 millisecond of arc detection. Thus, power may be disconnected within 40-50 milliseconds before it can cause significant damage.
1 phase, non-directional, Over Current or Earth Fault Relay
The relay can be used for feeder protection in all low voltage, medium voltage sub-stations. The relay has a built in high set facility. DIP switches are provided on the front panel for pick up and time delay settings
nX Series offer you numerical type 3 phase overcurrent & Earth Fault Relay. Its microcontroller based design offers you to choose from various field selectable IDMT & definite curves.
MD32-G is three-phase percentage biased differential protection relay for generators and rotating machines, with stator earth fault or restricted earth fault element.
MG30 / MG30-I is Multifunction Microprocessor Relay for protection of medium/large synchronous generators. The relay measures the RMS of three-phase currents and voltages and computes the positive and negative sequence components of the Current system.
MRP11 is micro controller based single phase, reverse power relay with one measuring element. Relay operates for pure active reverse power only and will not cause spurious tripping due to PF fluctuations in the system. Relay can work as a reverse reactive power relay with an addition potential transformer.
The relay can be used protection of generators from reverse power conditions or in grid islanding systems for detecting mains failure or prevention of power flow from small generators to grid.
SC14S is a self-powered, single-phase, non-directional, Earth fault relay with one measuring element.
MM10 Relay is a microprocessor based Motor Protection Relay with 4 digits LED Display
MM30 is a Microprocessor based Comprehensive Motor Protection Relay designed for Medium and Large Motors
MPR300 is a Microprocessor based LT Motor protection relay. The relay has got inbuilt CTs for motor sizes up to 50KW (i.e 88 A current)
