Electrical power systems can be dangerous, and they must be maintained regularly to keep them safe. A professional inspection can help identify problems and deterioration that can lead to electrical fires. These fires can damage a building, halt production, or even cause loss of life. In addition to boosting safety, regular tests can also help lower home insurance premiums.
The entry into the field of electrical testing is often an extension of a current job and may include journeyman electricians, utility workers, ex-military personnel or even technical programs at colleges that offer specialized electrical power skills. However, a professional must be aware of the many dangers that they face and be properly trained to perform their duties.
It is vital for an electrician to be familiar with a wide range of electrical testing procedures in order to be able to provide their customers with the best possible service. For example, they will need to know how to conduct an earth leakage test. This involves measuring the current that flows through a device and then determining where it is leaking to earth. This process can detect any faults or leaks in the equipment that could result in a shock to the operator.
Another important testing procedure is a dielectric voltage withstand test, or hipot test. This is done by applying a voltage much higher than the operating voltage of a device or installation. The purpose is to put the electric insulation under stress that will not degrade it. This can be used to determine the quality of an insulation and to find any problems with it such as cracks or voids.
It is also important for an electrician to be familiar with the requirements of the National Electrical Testing Association (NETA). NETA is an ANSI-accredited standards writing organization that defines the specifications that equipment must meet before it can be deemed safe and reliable. NETA requires that its technicians be properly trained to meet these standards.
There are several different types of electrical testing, including high voltage, insulation resistance, and grounding tests. Each type of electrical test has its own purpose and provides unique information. However, there are some common tests electrical testing companies that can be performed by all electrical testing companies. These tests include the ability to locate and trace shielded cables, voltage testing, primary injection testing, arc flash hazard analysis, load flow studies, and short circuit analyses.
Having the proper knowledge and experience to perform these tests can ensure that a facility will be able to identify and fix problems before they become dangerous. This will prevent unnecessary production downtime, costly repairs or loss of life.
