Testing relays and their circuits in vehicles doesn’t always require a trip to the bench. With a few simple tools and ...

Ground fault protection is a cornerstone in ensuring the safety and operational reliability of modern power systems. Ground faults, which occur when an unintended electrical path connects a live ...

NK Technologies (www.nktechnologies.com) introduces the DG Series DC Ground Fault Detector. The DG series was designed to keep operators and machinery safe from accidental shocks by detecting fault ...

The Vigirexâ„¢ ground-fault relays are designed for use on equipment, such as HVAC units and manufacturing machines, used in industrial and commercial facilities. These ground-fault devices are ...

Tripping is three-pole, with mho phase fault protection , and ground elements mho or quadrilateral--the latter especially for short line and cable applications. The advanced differential protection ...

This is true if the ground fault is from a conductor to its own metallic shield. However, testing has shown that only 3% to 14% of the available ground-fault current will flow through each cable ...

There are many typical problems found during the testing of ground-fault systems that may prevent proper ground-fault operation. For instance, on 3-phase, 4-wire systems, the neutral conductor should ...

The new ground fault relay also provides features for automated monitoring and control in power distribution panels, switchboard installations, municipal utilities, elevators, new construction sites, ...
