Generator Neutral Grounding Resistor

Product Description

We feel proud to introduce ourselves as the leading manufacturer, exporter and supplier of LT Neutral Grounding Resistors that are used for maintaining power load in earthing. To manufacture our provided resistors, we utilize high quality raw material with the help of advanced technology in sync with international standards. We present these resistors in various specifications to rally the requirements of the clients. Rigorously tested on certain parameters of quality, our offered LT Neutral Grounding Resistors are available at most competitive prices.Features ofLT Neutral Grounding Resistors: Termination kitHaving Safety Screen for enclosuresSupporting Pedestal structures systemHave Cable gland & stand off insulatorsHaving Earth fault leakage Relay facilityResistors having high potential transformersResistors having excellent stainless steel hardwareHaving aluminum enclosure and hot dip galvanized enclosuresSuitable for both neutral grounding transformer / excitation transformer Advantages ofLT Neutral Grounding Resistors: Having non anti frost heating facilityNeutral Grounding resistance value is preciseNeutral Grounding Resistor are easier to installGrounding Resistors require virtually no maintenanceGrounding Resistors valve remain constant throughout lifetimeGrounding Resistors temperature have shorter time constant facilitySuch Grounding Resistors have longer life and having nor anti condensation heatersNeutral Grounding Resistor require constant maintenance due to evaporation of gel and electrolyte the liquid resistors Product Information: Having various types of Enclosure facilityCan be install both in Indoor or outdoor locationsDuty rating 10 sec., 30 sec., 60 sec., & continuous etcHaving both system voltage and operating voltage systemGrounding Resistor temperature can rise over ambient temperatureAlso having material for enclosure (protection class as per IS-12063)Accessories Require such as space heater, current transformer, isolating switch on load & off load, manually or motorised Product Specifications: Rated Voltage : For neutral grounding / earthing resistor rated voltage means line- to neutral voltage i.e. System Voltage divided by root3 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. IS-3043 recommends 30 sec. rating.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 (if required).Material of Resistance Element : We offer resistor elements made from any stainless steel or FeCrAl 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.Temperature Rise Allowed: Normally Temperature rise is restricted to 375 deg.c. above ambient temperature as per BS-587. It can be 760 deg.c. as per IEEE-32. It can be offered of any other temperature rise as per customers requirement.Construction: NGR include resistor assembly, plus required insulators, internal connections and hardware etc.Cabling / Termination : Suitable arrangement and clearance is provided for termination of cable, flats or bus duct as per requirement with undrilled removable gland plate.Specification Usage/Application Electrical Industry Brand National Resistors Max.
