OHMIC RESISTORS designs, builds and tests indoor and outdoor neutral earthing resistors (Neutral grounding resistors) to suit our customer’s ratings and environmental locations. Designs are from 240V to 132kV and 2 Amperes to 10,000Amperes. Products comply with customer specifications inclusive of ANSI /IEEE Std32-1972 standard for neutral grounding devices. Neutral earthing resistors can be installed in indoor and outdoor enclosures providing protection ranging from IP00 to IP56. Designs can incorporate short time or extended time neutral fault currents in accordance with customer specifications, times typically from 0.5 to 60 seconds. Enclosures can be suitable for connection at neutral and earthing connection locations with cable or bushings. Multiple earthing configurations, on load or off load isolating switches, neutral current transformers and enclosure heaters, as required by customer specification, can be incorporated in the end product. Enclosures can be designed for installations where space is limited. Enclosures, are manufactured utilizing Galvabond, powder coated mild steel, stainless steel or aluminium as required by customer. Designs are available for tropical and cyclonic locations. At OHMIC RESISTORS, we manufacture Dynamic Braking Resistors with thermal ratings to suit customer requirements within resistor design criteria. Designs may be air natural or force air cooled. The purpose of a dynamic braking resistor is, when inserted into a motor or VFVV drive circuit, to slow down an electric motor and upstream equipment by converting kinetic energy into heat. The design of dynamic braking resistors depends on cyclic ratings of given systems, for example electric locomotives or mill drives.
