Premium NGR Solutions for Transformers, Generators, and Industrial Power Systems. Ensure Safety, Limit Fault Currents, and Protect Your Critical Assets.
Engineered for Safety & Reliability: Our Neutral Grounding Resistor Solutions
At Orion Resistors, we specialize in the design and manufacturing of high-performance Neutral Grounding Resistors (NGRs). An Neutral Grounding Resistor is a critical component in electrical power systems, connected between the neutral point of a transformer or generator and the earth ground. Its primary purpose is to limit fault current during a ground fault, preventing damage to equipment and reducing safety hazards. Our NGRs are built to the highest international standards, ensuring operational continuity and system protection.
Protect the heart of your electrical distribution system with our specialized Transformer Neutral Grounding Resistor. When a ground fault occurs in a transformer, the uncontrolled fault current can cause catastrophic damage to the winding and core. Our Transformer Neutral Grounding Resistors are precisely calibrated to limit this current to a safe level, allowing sufficient flow for protective relays to operate and isolate the fault, while safeguarding your valuable transformer from irreversible harm. Ideal for utility substations, industrial plants, and commercial facilities.
Safeguard your prime power source with Orion's robust Generator Neutral Grounding Resistor. Generators are highly susceptible to damage from ground faults, which can stress the stator iron and winding, leading to costly repairs and extended downtime. Our Generator Neutral Grounding Resistors are engineered to limit the fault current to a value that is both safe for the generator and adequate for fault detection. This not only protects the generator's integrity but also minimizes mechanical stress and reduces arc-flash hazards, ensuring the longevity and reliability of your power generation assets.
