If you use a standby generator for your home or business, you know how valuable it can be during a big storm or any time when your power supply is uncertain. We tend to get a lot of big summer and winter storms in the DC Metro area, so having a standby generator is crucial for things like keeping food safe and keeping lights on. So if you want to make sure your generator works smoothly when you need it to, it’s important that you keep it well maintained!

After a major storm knocks out power, your generator could be running 24/7 for a few days. To prepare for times like this, here are some ways you can keep your generator in good shape:

In addition to these checks you can do on your own, it’s important to have your standby generator inspected by an authorized sales and service dealer. Remember—many home and commercial generators have a limited warranty and require service from a licensed technician in order to make sure the warranty can be honored.

Standby generator repair and maintenance requirements may vary significantly based on the type of generator you are dealing with. For instance, commercial generators are primarily the alternator type of generators. Alternators have stationary windings (which create the alternating current) and rotating windings (which create direct current). Since rotating windings usually go through a significant amount of friction when working, regular tune ups and electrical repair will see them needing to be replaced every once in a while.

Automation lies at the core of much of our modern lives. However, it evolves at radical speeds. The simple concept, to build a machine to perform a task without human intervention, was the engine of the industrial revolution. Now that concept is the driving force behind robotics, self-driving vehicles, and a wide range of advanced technologies.

Most automated tasks are part of a closed-loop system. This system is designed so that the outputs are monitored and fed back to the controller. The controller changes its operation as needed. An example of a closed-loop system is a home thermostat, which monitors the air temperature. When the low set-point is reached, a contact closes in the thermostat, beginning a furnace lighting cycle. As the furnace runs, the room air temperature increases until the high set-point is reached. The contact opens and ends the furnace burn cycle. This is automation.

With electrical relays, it is possible to achieve a variety of automatic functions. A motor starter uses a relay to close a contact that sends electrical power to a motor. In addition, it closes a set of auxiliary contacts that keep the main relay closed. A control mechanism, such as a temperature input or a stop button, can be wired in series with the auxiliary contact. This allows for control of the motor. An expansion of relay logic is the programmable logic controller or PLC. Instead of mechanical relays, a PLC uses a set of input and output contacts connected to a computer controller. Software in the controller then dictates how the inputs and outputs interact. They additionally execute specific patterns of operations, based on programmed ladder logic.
