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. Total with Tax 214. Are you a recert Yes No Are you currently working Yes Which pool will you be working at A copy of your responses will be emailed to the address you provided. The SIGMA monitoring relay measures the current through the NFR, the transformer neutral-to-ground voltage and the NGR resistance. An iGuard Representative will contact you to confirm next available date. 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. Time to complete this education training is 24 hours. This school offers 1 program which provide training for 1 qualification, including Boy Scouts of America (BSA) Lifeguard Certification. If an open or short circuit occurs, the relay will alarm. iGUARD Lifeguard Training LLC is located in Henderson, NV. 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. Be aware of threats presented by jelly-fish, sharks, crabs, and the myriad other swimming and crawling creatures that live along the coast.A major safety concern is the loss of neutral path, i.e. The ocean is home to millions of different life forms, but some visit shorelines and beaches more commonly than others.Red tide can kill marine life and cause serious illness in human beings. iGuard Lifeguard Training LLC Educational Services 9 YEARS IN BUSINESS (702) 481-4034 2190 Olympic Ave Henderson, NV 89014 CLOSED NOW 5. These toxins accumulate and cause red tide. (702) 558-1548 1054 Willjay Ln Las Vegas, NV 89123 4. Every year, certain colonies of algae, often referred to as blooms, produce too many toxins. Red tide can seriously effect the safety of swimming conditions too. Download CSA 1801746 Download A major safety concern is the loss of neutral path, i.e. ![]() ![]() Even the most experienced beach-goers can still be caught off guard. When waves break too close to the shore, they can be unpredictable, can knock people down, and can cause serious neck and spinal injury.
