What is Electrical Testing? Electrical testing refers to the inspection and testing of electrical systems in industrial plants, offices, water heaters, electrical power generators, and several other locations. To perform this, you must possess a working knowledge on the various electrical symbols, electrical instruments, circuit designs and wiring schematics. Special training in building and design working environments. Knowledge on electrical circuit theory, the various symbols used in electrical signals, and the proper use of test equipment. This knowledge can come in handy during troubleshooting.
Some companies hire electrical test engineers for the purpose of performing pre-test activities on gas turbine blades. There are several types of turbines and they all require pre-testing. One type of pre-test activity that most of these companies require their technicians to perform is the inspection of electrical components. Some of these companies have mechanical engineers, chemical engineers, or both, who are hired specifically for this purpose.
Before this, electrical test engineers must inspect the different parts of a system. Different types of electrical instruments are used in performing inspections. Some of these instruments include Ohm's tester, resistive load testers, electrical conductors, electrical isolators, voltage and current testers, and fuse holders. These instruments are placed in a specific location to meet customer requirements.
Nowadays, it is common for electrical test engineers to use specialized software to control, manipulate, view, and examine different types of electrical systems. These software programs are available for purchase. Some of them are available as desktop-based application that can be installed inside the company's main computer system. There are also labview-based software programs that can only be downloaded to the personal computers of test system engineers.
As mentioned earlier, electrical engineers use various types of electrical test methods. In order for engineers to effectively perform the task of functional test, they need to consider different factors, such as the type of equipment being used, the type of wiring system that will be used, as well as the factors of continuity and reliability. Other considerations include materials testing, circuit testing, and level testing. The most common types of functional tests involve resistance testing, which is performed with the help of load cells, and frequency testing, which make use of devices that measure and control the frequency level of operation.
As mentioned earlier, electrical test engineers also need to consider factors of reliability and continuity. However, there are some electrical test scripts that are capable of achieving both of these objectives at the same time. This type of test scripts are more advantageous than functional or resistance-based tests because they can detect even minor failures. Furthermore, they can generate accurate electrical test reports that can be used for a wide variety of purposes, such as preventing false alarms, improving productivity, identifying control problems, identifying performance problems, and so forth.
When it comes to selecting a particular electrical test engineer, one of the things that you have to take into consideration is the person's experience in this specific related field. Electrical engineers usually have two to three years experience in the related field. Moreover, they must have passed through many different sets of examinations and have been certified by numerous accrediting bodies. Apart from having a number of years experience, they should also have a lot of hands-on training, particularly on the topics related to electrical engineering. Having been exposed to a wide variety of topics and situations will greatly improve their capability in solving electrical engineering problems.
Electrical engineers are not only capable of detecting faults in electronic products. They are also capable of troubleshooting problems in a timely manner, as well as resolving problems in production processes. Electrical engineers are highly needed in manufacturing firms because they are responsible for troubleshooting and repairing electronic products during the manufacturing process. Without these engineers, the production process would surely come to a halt.
