Off-site stray, or neutral-to-earth (NE), voltage can result from primary neutral currents, off-site faults, or marginal groundings. Ronk BLOCKER® is designed to reduce the off-site contributions to the stray voltage, allowing the utility to focus on the on-site sources.
The device operates directly on the principle of magnetic saturation and does not depend on external controls or internal logic signals; therefore, it reacts instantaneously, providing immediate, continuous protection at all times.
