Relay Technician or Engineer
In track and field, a relay is a race run by a team. As one athlete approaches the next athlete in the relay, the baton is handed off to the next runner, and the baton thusly makes steady progress all the way around the track, with each athlete allowing the baton to advance the determined distance. In electrical components, a relay is a switch operated by electricity. These switches may be controlled via electromagnets, which is the most common method today. And in order to make sure that all of the relays are working properly, there must be a relay technician (or engineer) employed to maintain it and any other relays in the vicinity.
In the energy industry, relays are used to control multiple circuits that must be linked to the same signal. They require complete electrical isolation from the control and the controlled circuit in order to work. The first use of relays was for telegraphing through long distance telegraph circuits. In the modern day, relays are still used in telephones and computer circuitry. But their most common use is still in the field of energy. This means that the energy industry has the greatest need for an experienced relay technician (or engineer).
A relay technician (or engineer) is not only responsible for relays, but are usually also responsible for contactors: a type of relay that is directly linked to a motor and is designed to handle high power. It's important that the components of any given relay are protected in whatever ways possible in order to prevent damage or premature wearing out of the components. Solid-state relays, for example, rely on semiconductors instead of physical switches. Protective relays employ multiple operating coils and other precautions to prevent the relay from faults and from being overloaded. After all, there's no point in having a relay that will blow out at the first sign of overloading.
Relays in the energy industry can be used to control the flow of energy. They can also be used in conjunction with transformers to change the voltage or current of an electrical flow before being distributed out to its intended recipients. It's also an energy saving measure, since it prevents electricity from hitting residential homes as well as businesses from getting hit with a full-force electrical surge. The relay technician (or engineer) is not only in charge of maintaining the relays, but also for evaluating their usage and changing the output according to need.
Much like a generator itself, a power plant has many parts and components that are vital to its performance and efficiency. A power plant needs people who are knowledgeable and experienced about the inner workings of a power plant so that they can be trained to anticipate when certain areas will need more energy and when others will need less. This makes sure that the energy generated by the power plant isn't wasted, and that it's put to good and efficient use on the power grid.
Becoming a relay technician (or engineer) requires you to complete an undergraduate degree, preferably in physical science or one of the many branches of engineering, especially electrical engineering. But a bright career is worth the investment, and when you're working with electricity, you know better than most what it means to have a brilliant career.
