![]() ![]() The relay compares the measured values against the field settings of the relay and provides relay outputs and LED indications when an abnormal condition is detected. The SIGMA monitoring relay measures the current through the NFR, the transformer neutral-to-ground voltage and the NGR resistance. In distribution systems employing resistance grounding the SIGMA monitoring relay protects against ground faults and abnormal conditions in the path between system neutral and ground possibly caused by loose or improper connections, corrosion, foreign objects or missing or compromised ground wires. The I-Gard SIGMA monitoring relay is a combination neutral grounding resistor (NGR) monitor and ground fault relay. If an open or short circuit occurs, the relay will alarm. ![]() With the Sigma monitoring relay the neutral path from neutral to ground (including resistor) is continuously monitored for integrity. The result is changing from a high-resistive grounded system to either an ungrounded or solidly grounded system without anyone knowing it! This would cause severe safety hazards, such as transient over-voltages, unlimited fault current, escalating arcing faults etc. broken wire from source neutral to resistor or between resistor and ground or even a bad or loose connection. ![]() Here are a few… Bridging the gap between training and reality is.A major safety concern is the loss of neutral path, i.e. One concept and approach in this training is to INVESTIGATE your.īy Natalie Livingston | | UncategorizedThrough the course of completing over 700+ accident and drowning investigations, we believe there are important lessons to be learned from each incident individually as well as collectively.
