We are offering Load Banks for Generator Testing to our clients. The generators are designed to provide power to faculties at times of emergency or power cuts. The factories, commercial buildings, offices, schools, colleges, malls, etc., keep backup power sources in form of generators to assure the regular supply of power and prevent hindrance. If properly maintained, gen sets will continue to get into action on a moment’s notice during an emergency. In the generator maintenance plan, load bank testing is important to assure it is completely reliable and operational. The load banks for generator testing is available here. This test is performed to check the performance of generator engine.

This device places an artificial load on the generator in order to bring its engine to desired operating temperature as well as pressure level. The generators that are only used for the emergency purpose and are no exposed to frequently carrying heavy loads, must be tested by load banks.

Known for its smooth functioning and wide application areas, our range of Neutral Grounding Resistors is extensively demanded and availed by our clients at the most reasonable and competitive prices. Besides, our expert team give special care to the quality aspects of our offered products.

 

Feature:


  • Robust construction

  • Compact design

  • Durable

 

Product detail:

 

  • Rated Voltage : For neutral grounding or earthing resistor rated voltage means line- to neutral voltage i.e. System Voltage divided by root 3 i.e. 1.732

  • Rated Current : Means Initial current that will flow through resistor when it is cold. Normally Full load current value is same as Rated current

  • Time Rating : It is length of time for which NGR must tolerate rated voltage

  • Short Time Rating : Normally it is 10 sec. or 30 sec. or 60 sec. depending on design parameters of protection system

  • Continuous Rating : It is normally 10 % of full load current for healthy system neutral grounding resistor to be designed for continuous rating of 5 % to 10 % of full load current

  • Temperature Rise Allowed: Normally Temperature rise is restricted to 375 deg.c. above ambient temperature as per BS-587

  • Cabling or termination : Suitable arrangement and clearance is provided for termination of cable, flats or bus duct as per requirement with removable gland plate

  • Construction: NGR include resistor assembly, plus required insulators, internal connections and hardware etc

  • Material of Resistance Element : We offer resistor elements made from any stainless steel or Cu-Ni or Ni-Cr or any other resistance material as per requirement. Normally formed stainless steel element are best and economical for NGRS

Neutral Side Cubicles and generator outlet are generally used for the connection of power terminals of the generators to other systems. Neutral side cubicles are also known as Main Terminal Boxes-MTBs. These cubicles have the required protective and measuring devices. A connection point is provided on the cubicle outlet for the encapsulated conductors or power cables. Depending on the size and construction of the genset, the number of cubicles varies. One design includes a single common cubicle for neutral and outlet point. The second design has two separate cubicles, one for the outlet devices and second for the generator neutral point.

Neutral side cubicles are generally equipped with the voltage & current measuring, protection transformers, RC elements and surge arresters. The said RC elements play the role of over-voltage protector. These are custom designed and made by us, hence each solution is individual and personalized, ensuring more efficiency.
