Low and High Resistance Medium Voltage Grounding System

Neutral Grounding Resistors and Reactors have “low impedance grounding.” They will reduce the stress and amount of damage to your power system equipment. They do this by controlling the magnitude of the ground fault currents. When used in generator neutral, these devices will also limit the amount of the generator available Line to Neutral fault current below the design limits. These limits are set by the NEMA MG1 generators design standard.

Neutral Grounding Resistors and Reactors will reduce the magnitude of harmonic currents. They will also help switchgear sense that there is current in neutral/ground. The NGR’s help dissipate that current.

Standard Enclosure:

  • Filtered ventilation louvers
  • NEMA 1/3R for indoor/outdoor applications
  • Hot Dip Galvanized
  • Bottom Entry/Exit

Enclosure Options:

  • Aluminum, Stainless Steel (304 or 316)
  • Powder coated ANSI 61 Gray or custom colors
  • Connection Bushings:
    One or Two / Top or Side Mounted

Neutral Sensing & Monitoring:

  • Window Type or Bar Type Current Transformer

Key Features of Busbar Boots:

Insulating busbar boots are specifically designed to provide a protective covering that insulates and shields the busbars from potential hazards. By mitigating the risks associated with exposed busbars, these boots significantly improve the overall safety and reliability of electrical installations.

Bus boot is flexible electrical insulating boot / shroud for busbar and switchgear connections upto 36KV. These pliable boots can be installed, removed or replaced in few minutes. Made from specially formulated Polyvinyl Chloride (PVC) material to provide excellent electrical insulation and to withstand higher operating temperature continuously.

Bus boot provides reduction in air clearance, which helps designing compact panels; thereby reduces the material costs saving in busbar lengths, sheet metal components, etc.

  • High Dielectric Strength: Busbar boots are manufactured using materials with excellent dielectric strength, ensuring effective insulation and preventing electric arcing.

  • Resistance to Environmental Factors: These boots are designed to withstand various environmental challenges, including moisture, chemicals, and UV radiation, ensuring long-term durability.

  • Customization Options: Busbar boots are available in various sizes and designs, making them adaptable to different busbar configurations and installation requirements.

  • Easy Installation: Busbar boots are easy to install and remove, allowing for swift maintenance and replacement when needed.

Key Features of Standoff Insulators:

  • Electrical Isolation: Electrical standoff insulators isolate conductors and electrical components from the surfaces or structures they are mounted on. By maintaining this separation, they prevent the flow of current and reduce the chances of electrical arcing or leakage.

  • Preventing Corrosion and Contamination: These insulators, are made from materials resistant to corrosion, help protect electrical components from environmental factors like moisture, dust, and chemicals that could lead to premature wear and failure.

  • High Dielectric Strength: These insulators are manufactured from materials with excellent dielectric properties, ensuring they can withstand high voltages without becoming conductive themselves. Molded insulators have a higher heat resistance and a higher moisture resistance when compared to the regular plastic insulators. Hi-Pot tested to assure electrical reliability. – These molded insulators also have closer height tolerances and higher shatter resistance when compared to ceramic insulators.

  • Customizability and Testing: Insulators are available in various shapes, sizes, and materials, allowing for customization to meet specific application requirements. Electrical standoff insulators  offer both the mechanical and electrical requirements of IEEE, IEC, NEMA and ANSI Standards. Testing is also performed in accordance with the applicable industry standards.

Applications for Standoff Insulators:

  • Power Transmission and Distribution: Insulators are used in overhead power lines, transmission towers, and substations to support conductors and maintain safe electrical clearances.

  • Electrical Panels and Switchgear: Standoff insulators help isolate and support electrical components within control panels, switchgear, and circuit breaker assemblies.

  • Renewable Energy: Standoffs are also used in solar power systems, renewable energy sectors to provide electrical isolation and support for power cables and equipment.
