Low-voltage power distribution & control systems

Low-voltage high resistance grounding

Eaton’s high resistance grounding system limits the magnitude of current during a ground fault, reducing arc flash energy to increase personnel safety and minimise the failure of motors, transformers, power cables and other equipment. Providing integrated fault tracing for easy detection, this solution is ideal for critical applications such as industrial, oil and gas, petrochemical, healthcare and utility.

High resistance grounding

Low-voltage high resistance grounding systems

Grounding is commonly used in the electrical industry to mean an intentional connection to conductive materials either solidly or through impedance. An ungrounded system is a system, circuit or apparatus in which there is no intentional connection between the system conductors and earth.  A system may still be considered ungrounded if there is a possible connection to earth ground through potential measuring devices or very high impedance devices. High resistance grounding, mainly used in low-voltage systems, most common in 480 V and 600 V systems, this arrangement means that a certain resistance has been intentionally put between the neutral point of a system and earth ground.

Factors to consider when choosing a grounding system:

  • There is a need for service continuity after the first ground fault
  • There is a need to be able to easily locate ground faults
  • There is no need to serve line-to-neutral loads
  • If there is no available neutral, it will be necessary to create an artificial neutral
  • It will be necessary to estimate, calculate or measure the capacitive charging current of the system
  • The magnitude of maximum current acceptable on the system under ground-fault conditions
