Manufacturer & Exporter of Starting Resistors. Our product range also comprises of Load Banks and Braking Resistors.

Features :

• This resistor allows a stepped starting having high starting torque with low and limited starting currents. Suggested for high power motors and to drive equipments with strong inertia and needs of fast accelerations and heavy, long and frequent startings
• This resistor is used for gradual starting with the possibility to choose the torque in relation with the device to start. Suggested for equipments with low starting torque and increasing advancement

When an induction motors rotor is turning slower than the synchronous speed set by the drives output power, the motor is transforming electrical energy obtained from the drive into mechanical energy available at the drive shaft of the motor. This process is referred to as motoring. When the rotor is turning faster than the synchronous speed set by the drives output power, the motor is transforming mechanical energy available at the drive shaft of the motor into electrical energy that can be transferred back to the drive. This process is referred to as regeneration. Most AC PWM drives convert AC power from the fixed frequency utility grid into DC power by means of a diode rectifier bridge or controlled SCR bridge before it is inverted into variable frequency AC power. Diode and SCR bridges are cost effective, but can only handle power in the motoring direction. Therefore, if the motor is regenerating, the bridge cannot conduct the necessary negative DC current, the DC bus voltage will increase and cause an overvoltage fault at the drive. More complex bridge configurations use SCRs or transistors that can transform DC regenerative electrical power into fixed frequency utility electrical energy. This process is known as line regeneration. A more cost effective solution can be provided by allowing the drive to feed the regenerated electrical power to a resistor which transforms it into thermal energy. This process is referred to as dynamic braking.

features :neutral grounding resistors are used in star connected systems to protect the transformer / alternator from severe damage caused in event of an earth fault. we manufacture neutral grounding resistors for all current ratings upto 3000a and for a voltage range from 230v to 36kv. the resistors can be designed in cast iron grid, rod formed grid, wire wound and punched grid form. advantages of using a neutral grounding resistor:reduced operation andmaintenance expenses.fast isolation of the original fault.reduced transient over voltages.reduced physical damage on theequipment at fault.simplification of ground fault location.increased life and protection oftransformers, generators andrelated equipment.reduced frequency of faults.improved service reliability.increased protection in the use of lightning arresters.increased safety for personnel
