    Resistance Boxes

    Request for Price

    The Resistance Boxes are used for heavy duty requirements of controlling the current in the circuit for various applications. Starting and speed control of AC Slip Ring motors with Resistors is a universal method. The resistor is used to limit the inrush current and control the torque and speed characteristics of an AC Slip Ring Motor.By changing the resistance in the Rotor Circuit in various steps (thru a Contactor), the starting torque and speed of the motor can be controlled to the desired value.     APPLICATIONS : • EOT CRANES & WINCHES • RUBBER MILLS & FLOOR MILLS • COAL MINES & SUGAR MILLS • STEEL PLANTS & CEMENT PLANTS • POWER PLANTS & PAPER PLANTS

  • Neutral Grounding Resistor

    Neutral Grounding Resistor

    Request for Price

    NEUTRAL GROUNDING RESISTOR (NGR) is used for the resistance grounding of Power Systems. Earthing through Resistor is the most common, economical and effective solution for impedance earthing. It is used, when the Neutral of the supply transformer is available and its own impedance is not enough to limit the fault current. Inserting a Resistor between the Neutral of the Generator/Transformer and Ground serves to limit the maximum Fault Current to a predetermined value. This value is low enough to prevent damaging Fault Currents to the generating, distribution and other associated equipments; yet high enough to operate fault clearing relays.

  • load bank

    load bank

    Request for Price

    Load Bank Resistors are used to act as resistive loads for testing critical power supply sources . Typical applications are : • Testing batteries • Periodic testing of standby generator sets • Factory testing of generator sets • UPS System testing • Balancing diesel generator loads for cleaner air emissions. Load Banks having different steps of resistance, can be supplied alongwith associated control panels to switch on resistance values, as required , to test different capacity of generators / transformers with the same Load Bank. AC & DC Load Banks are manufactured as per Customers' requirements in various ratings ranging from 1 KW to 3000 KW.Load Banks are designed for natural air cooled or for forced air cooling, depending on the wattage rating, to minimise the size and cost of the system. A Blower (Exhaust fan), mounted on a frame structure, is provided in the bottom of the Load Bank for upwards flow of air draught. The top of the Load Bank is provided with a wire mesh for a free air flow.
