Protection of 3 Phase devices against Over voltage, Under voltage, Single Phasing, Reverse Phasing & Unbalance Supply are one of the major issues in electrical systems. For safe running of 3-phase devices, special protections that keep a continuous watch on supply conditions are very essential. The major cause of maximum load burn-out is overloading which occurs due to Unbalance Supply, Single Phasing & Reverse Phasing conditions. VMR-3P detects such Conditions & protect the load from burn out.VMR-3P offer above protections along with 3 digit display showing. R-Y, Y-B, B-R voltages in scanning mode with precise accuracy. low/high voltage tripping to ensure trouble free running of 3-phase Loads.   Features :■ Voltage protection along with digital voltage readout■ Wide range of supply variation■ Unit will also work if any one phase is present■ Protection against Under voltage■ Indications for Low voltage, High Voltage, SPP & Relay ON■ Message Display for SPP, Reverse Phasing ■ Protection against Over voltage■ Phase unbalance protection■ Reverse Phasing Protection can be able to bypass through settings■ Single Phasing & Reverse Phasing protection■ No separate auxiliary supply required■ All the set points settable by keys

Motor Pump Protection Relays are useful for protection of 3-phase AC induction motors against various hazards. With their unique advantages they eliminate use of a thermalbimetal relay for motor protection. Being current sensing, they are to be selected according to motor rating and are available for practically all ranges of motors.

This unit is designed to sense the open circuit and over current drawing of the solenoid during its Energization time (typically within 20mSec. to 200mSec.) and to give latchable relay output when input solenoid current exceeds the set value.

Features: • DIN rail mountable • LED indication for relay status • External power supplySignal supply selectable by jumper. • Input voltage can be ACDC of up to 2000V Applications: *Voltage safety monitoring *Overvoltage monitoring *Configuring speed dependent relay by connecting analogue tachogenerator output to the module *Safety voltage monitor in Solar panel

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. etaCON L Series: Available steps: 3, 5, 7, 8, 12 Compact size (96 × 96 mm) in 3, 5, 7 steps version Automatic recognition of current flow direction Auto / Manual Control Online display of PF, Voltage, Current, kVAr, capacitor overload and Panel temperature Average weekly power factor measurement Capacitor over-current and panel over-heating protection No-voltage release protection function Last two can be programmed for Capacitor switching / Alarm / Fan Control Keypad locking function

The PFR-X power factor controller calculates the active and reactive power in the mains from the measured current and voltage.The intelligent control algorithm optimizes the switching sequences and guarantees for short regulation times with minimum number of switchings.At the same time, switching operations are equally shared among the available capacitor branches where possible.The integrated connection control immediately detects in which phase voltage and current are measured, and adapts the entire system automatically.The very low current threshold of 10mA allow for very reliable and exact PF control.1A as well as 5A current transform can be used without additional manual adjustments.The power supply cover a voltage range of 90....550V.

Reed relays in both form A and B contact configurations, this proven design is fully approved to MIL standards of bump, shock and vibration and features one of Crydom’s in-house manufactured, high vacuum reed switches for unsurpassed RF performance and reliability.

The first protective relays were electromagnetic devices, relying on coils operating on moving parts to provide detection of abnormal operating conditions such as over-current, over-voltage, reverse power flow, over- and under- frequency. Microprocessor-based digital protection relays now emulate the original devices, as well as providing types of protection and supervision impractical with electromechanical relays. In many cases a single microprocessor relay provides functions that would take two or more electromechanical devices. By combining several functions in one case, numerical relays also save capital cost and maintenance cost over electromechanical relays. However, due to their very long life span, tens of thousands of these "silent sentinels" are still protecting transmission lines and electrical apparatus all over the world. An important transmission line or generator unit will have cubicles dedicated to protection, with many individual electromechanical devices, or one or two microprocessor relays.
