WebOct 29, 2024 · The ground-fault current returns through the CT in the neutral-bus to ground-bus connection. For feeder circuits, an insulating segment may be introduced in busway or conduit, as shown in Figure 4, and a bonding jumper connected across the insulator to carry the ground-fault current. A CT enclosing this jumper then detects a … WebMay 1, 2024 · Guide to Ground Fault Sensing. Will Delsman May 1, 2024 Electrical Fundamentals May/June 2024. Ground faults arise when current flows from an energized conductor to ground inadvertently. The return path of the fault current is through living beings or equipment touching the grounding system. Ground fault detection is critical to …
WebGround fault protection (GFP) devices do not sense the small (< 1 amp) current leaking in a ground fault, hence why it is called a “blind spot.” In the event of a second fault with larger current in which the GFP would …
Before we can define a ground fault, we should quickly specify a fault in general. Any type of electrical fault is, essentially, an abnormal flow of electricity. Electricity is intended to stay within its electrical current, and when the electricity goes astray, a fault occurs.
