Electrical current will always take the path of least resistance if given a choice. When the connection involves a human being, there can be a severe shock resulting in injury or even death. When caused by poor design or equipment failure, the cost is reflected in destroyed systems and a greater chance of liability for associated injuries. Ground fault system certification helps ensure the highest levels of inspection and safety compliance.
Even though it is assumed that any modern building or equipment containing electrical systems will be grounded properly, each situation has its own unique requirements. In cases where maintenance has been delayed or if mistakes were made in the original circuit design, there may be the potential for an arcing, low-level ground fault. This phenomenon produces effects similar to arc welding, and can destroy switching gear.
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.
The certification that NETA provides for employees helps ensure competency when dealing with potential hazards, and deals with existing issues using accepted safety procedures. Each individual must conform to the minimum industry requirements for experience, and complete all necessary training. These employees are also required to provide impartial and independent analysis.
Insurance companies recommend annual testing. The cost involved varies, depending on the type of equipment, the scheduled timing of the event, and the actual topography of the site. Coordination with local utilities may be required, which testing companies arrange. A system that is in good working order will be able to detect and correct problems instantly, potentially saving thousands of dollars in unnecessary repairs.
