Product Details:

Single line to Ground Fault - Loading Resistor are designed for ground power systems by using a resistor between the system neutral and ground. This product minimize the prospective ground-fault current to a pre-established value. With a properly placed resistance-grounded system gives benefits over both ungrounded and solidly grounded systems. This resistors functioned as the system is grounded, temporary overvoltages do not show and groundfault current can flow, allowing it to be known and measured. The resistor also used when it is grounding the system, the large and destructive ground-fault currents of solidly grounded systems are unknown. Meanwhile, the ground-fault relays is used on feeders to give selective coordination and to quickly place or isolate the fault.

Product Details:

Neutral Grounding (or some time name Earthing) resistor systems protect power transformers and generators from damaging fault currents. Earthing of the neutral limits the ground fault current to a high level (typically 50 amps or more) in order to operate protective fault clearing relays and current transformers. These devices are then able to quickly clear the fault, usually within a few seconds. The importance of this fast response time is that it:

• Limits damage to equipment
• Prevents additional faults from occurring
• Provides safety for personnel
• Localizes the fault
• UL Listed
• CSA approved up to 7200v
• Seismic Zone 4 Certifications and type tests also available

The limited fault current and fast response time also prevent over-heating and mechanical stress on conductors. Please note that, like the solidly earthed neutral system, the circuit must be shut down after the first ground fault. Neutral Earthing Resistors are typically rated 400 amps for 10 seconds, and are commonly found on medium and high voltage systems.

Features & Capabilities:

• Neutral Earthing Resistors protect power transformers and generators from damaging fault currents
• Available for systems rated 240v to 72kv line-line (CSA approved up to 7200v)
• Stamped stainless steel grid or edgewound design
