LT APFC SYSTEM : - Reactive Power compensation system is designed to work automatically on LT power supply to measure , display & connect, disconnect the required capacitor banks through Thyristor /Capacitor Duty contactor with protection of MCB / HRC Fuses & series reactors to each bank to achieve the set Target power factor.

Thyristor /Contactor Switched Automatic power factor system is the highly accurate, properly designed system with required creep age distance as per required standards. APFC System equipped with advanced, Digital Microprocessor based relay to measure, calculate and display all electrical network parameters. It accurately measures cycle to cycle reactive power requirement for required capacitors are connected to switching element / device installed in the system, so as required capacitors are connected / disconnected to the network.

APFC Controllers close loop fast response multi method switching [MMS] algorithm helps system to have close & precise control on power factor.

APFC Relay has memory storage model of capacity 45 Days on hourly basis with Rs 232 port for communication.

led based light fittings :

pole mounted street light fitting with light-emitting diode:- solid-state light fittings are with simplified headpiece structure, excellent heat dissipation solution, natural beauty, perfect performance with special optical lens, high brightness led and other high quality electronic components are all combined & assembled into one unit to give maximum light output. It operates in a solid state i.e. There are no movable parts or chemicals used to produce light. Important components are the led, the driver and the lens. Temperature control & heat dissipation from the junction is such designed that the efficiency and longevity of led lamps is high & desired.

led lamp fittings with effective heat dissipation, high & long lasting lumens output performance, is unique solution in power saving field. Dimensions & weight of the fittings is as per wattage capacity .construction type is waterproof, sealed with gasket, useful for outdoor duty applications, manufactured in die-casting aluminum material with tamper proof glass lamp holding hook, fastened by screws & proper arrangement of fixing to give wide angle light spreading.
