Neutral Grounding Resistor(NGR): NGR is employed in AC distribution networks to limit the fault current which would flow from the transformer or generator neutral star point in the event of an earth fault in the systems. It is used when the neutral of supply transformer is accessible and its own impedance is not enough to limit fault current. The rating of the protection relays within the required time. For Grounding Neutral of Transformer or Generator, Resistors upto 33 KV are offered for fault of short duration like 10 sec., 30 sec., 60 sec., continuous etc. Material of resistor is no

PURPOSE Neutral Grounding / Earthing Resistors are employed in AC Distribution Networks to limit the Restricted Earth Current to a safe value which would flow from the Transformer or Generator star point in the event of an earth fault in the system without exceeding specified temperature limits. In case of short time rating, dissipation is negligible & the temperature rise for the resistor element depends on its capacity to store the energy generated in proportion to the mass & specific heat of the material used. Theses NGR,S are connected between the neutral point of transformer

Our compactly designed range of load bank is a device used for developing electrical load and applying the same to an electrical power source to convert or dissolve the power output resulting from it. The load provided by the load bank can be effectively controlled with the aid of control devices, resulting in suitable functioning. Following are its application area: UPS system testing Testing the functioning of turbines Battery system testing Load optimization in heavy duty power applications

Motorised Isolator Panels(NIS) with CT & PT: We design and develop an array of neutral isolator panels (NIS) with CT & PT that are highly reliable and yield better operational level. These products require less maintenance and are used operational Used mechanically strong fiberglass link instead of epoxy link to avoid regular problem. These panels can easily be mounted on the walls or any kind of switchboards and are available in single pole or three pole type. Our neutral isolator panels (NIS) with CT relay come with the following ratings: 3.3 KV./6.6 KV./12 KV./22 KV./33

DYNAMIC BREAKING RESISTOR In electric braking, traction motor acts as a generator. Kinetic Energy of a moving train converted into electrical energy is, dissipated in the form of heat. This is called ‘Dynamic Braking. Construction: Dynamic Braking Resistors are manufactured as per Customers requirement. Testing: All Routine Tests are conducted in-house. Following special tests are also conducted if required, Vibration Test Rain Test Hygroscopic Test. ISOLATORS HT indoor isolators of following rating 3.3 KV / 6.6 KV/ 12 KV / 22 KV / 33 KV.
