Wire Wound Grid Type Neutral Grounding Resistor

Approx Price: Rs 60,000 / Unit 
Wire Wound Grid Type Neutral Grounding Resistor

Attributes:
  • These Resistors are economical for low current
  • Available in ratings of 1Amp and above
  • Resistance wire is wound on Ceramic Insulator to form a Coil for Wire wound
  • Mapping can be taken at any place

Features:
  • Resistance Wire is wound on Ceramic Insulator to form a Coil for Wire wound
  • Tapping can be taken at any place
  • These Resistors are economical for low current
  • Available in ratings of 1Amp and above
  • 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. These NGRS are connected between the neutral point of transformer/generator the earth.
  • In Earth, fault condition the Restricted earth fault current passes through the Metallic Resistor protecting the system till automatic protection takes place by absorbing the earth
  • Line to neutral voltage rate
  • Normally Full load current rate is same
  • Initial current flow through resistors when it is cold
  • Time length rate for NGR must tolerate rated voltage.
  • NGR construction includes resistor assembly, internal connections, plus required insulators, etc.
