Any electrical circuit will take the nearest route to a grounded surface when given the opportunity. If a person becomes the connector, the resulting shock may be damaging or fatal. If the phenomenon is the result of malfunctioning equipment or poor engineering, the cost can be measured in destroyed equipment and increased liability for injury. Ground fault system certification helps maintain higher levels of safety and compliance.
Even though it is assumed that the electrical system and associated devices in a building always include proper grounding in the original design, each location is unique. If there were inadvertent errors in the original design or problems with the current wiring or equipment, the result can be a low-level arcing ground fault. This phenomenon can devastate switching gear with temperatures similar to those used for welding metal.
NETA, or the International Electrical Testing Association, claims that up to fifteen percent of all the installations they test have problems having the potential to cause damage or injury. Protections are required by the National Electrical Code in the United States, and include the installation of specialized sensors that are able to detect and clear problems in the milliseconds before they result in costly damage.
They work by determining that electrical current is both going out and returning properly. If the pathway is out of phase, the electrical current will commonly take an alternate route that offers less resistance. That can be a building steel framework, pipes, or interior conduits. Safety devices monitor them by using current transformers to detect whether there is any deviation in the route, and a relay logic device that determines the value and timing of tripping current.
Most electrical safety designs include mechanisms that trip a switch or circuit breaker in the event of trouble, and also include testing panels that are capable of simulating unusual events and responses. While useful in some situations, these systems are not always in compliance with the established standards set forth by the National Electrical Code. The preferred method is manual inspection.
Well-trained and certified technical workers provide the advantage of access to the latest technological developments that are associated with equipment and building circuitry safety. Test equipment and procedures are uniformly calibrated to high standards that do not vary according to individual preferences. Most inspectors retain thorough records regarding past issues, and document any new problems.
NETA also provides certification for workers that ensures competency, which includes the use of accepted safety procedures and full awareness of all potential related hazards. They must meet minimum requirements for industry qualification, and have completed the necessary experience and training. Employees must also comply with the standards of independent and impartial certification required for accurate results.
Annual testing is recommended by most insurers. The associate expenses vary according to the scheduling of the inspection, the system equipment involved, and even the physical location of the inspection. It may be necessary for the testing firm to time this procedure with the local utility provider. Systems that are well maintained can detect and solve current aberrations immediately, saving money in the long run.
