A ground fault relay is responsible for protecting a series of equipment against ground faults. A ground fault occurs when there’s an unintentional current path between a conductor and a grounded surface. When these scenarios occur the electricity from the fault will need to find the closest path to the ground through worn insulation, dust, or water in the environment. Having a quality ground fault relay in place will make sure that the ungrounded systems are protected and that people on the job site can be protected from a variety of failures. Output signals for ground-fault relays are sent through a remote meter and a programmable logic controller.
A ground fault relay has an online and offline mode which is designed to provide a continuous level of protection against all ground faults. Under normal conditions, these are devices that are not separately connected through a transformer. The alarm range and the time delay are completely adjustable. Metered loop connections in the LED indicators are also available here. When the loop is switched off there’s an imposed travel limit for the network and there are motor protection applications as well. This can protect all of the elements in crucial electronic systems such as motor windings, ground fault relays, and more. Products in ground fault relays include alarm relay contacts, switching capacity items, mounting style relays, and more. Ground fault relays are designed to meet the parameters of each customer and with terminal screws and features that will make it easier to control ground faults in hostile environments.
Product specifications can change for the needs of each customer including added voltage measurements, DC internal resistance, AC impedance and 50 to 60 Hz, response adjustment pots, maximum leakage and capacitance to ground, and maximum permissible DC stray voltage. The ground fault relays for these transformers have a series of parameters that will help control safety in various situations. The radiofrequency, thermal current rating, and more are all indications of what these relays can deliver for customers and the needs of their business.
