Industrial generators are nothing short of mini powerplants that run on diesel. They are an integral part of the production line, and keeping them running smoothly is a necessity. Stopping in the middle of production can lead to several problems, whether it’s a missed deadline, lost momentum, or simply the loss of a warmed-up component.
So let’s go over some of the key operating procedures for diesel generators (DG) as recommended by electrical contractors. These procedures ensure the safety of your production line and associated electrical systems.
Protecting Your Diesel Generator & Electrical Equipment
Avoid Backfeeding
Backfeeding happens when a diesel generator is in operation, supporting your electrical system, without the mainline being disconnected. As soon as the power comes back on, the main starts feeding electricity into the generator as well, forcing it to work in reverse. This puts an unnecessary load on both your generator and the electrical system.
It also energizes the industrial transformer, which has the potential to fry almost every single node in your network. You can avoid backfeeding by connecting generators to isolated electrical lines, separating them from the main.
Ensuring Ventilation
Because of the sheer size of industrial diesel generators, it is common for them to have their own area attached to a facility, or in a separate shed. And while it is recommended that the generator is placed outdoors, industrial generators may need to be placed indoors, especially in areas with a lot of rainfall.
Even if your facility is air-conditioned when the generator is running, the heat from your generator can make the surrounding environment feel like an oven. Ensure there is enough ventilation in the facility to dissipate the heat; otherwise, you risk overheating the generator.
This heat and the carbon monoxide released during operation are the primary reasons for diesel generators being placed outdoors.
Overloaded Generators Mean Overheated Circuits
An overloaded generator will start introducing heat energy into the transmission line, which in turn will mean blowing fuses, melting circuits, damaged diodes, and much more. There is also a risk of fire, a massive danger for industrial areas. A fire involving diesel generators can spread quickly.
Refueling
It is never a good idea to refuel a generator while it is hot. It must be allowed to cool down first; otherwise, the diesel could catch fire. The larger a generator is, the more time it will need to cool, even after normal operation.
Electrical contractors recommend checking whether the hose is secure or not at least twice before opening the valve.
These best safety and precautionary measures for diesel generator units can help you avoid unnecessary accidents and keep your electrical system(s) safe, even during power outages.
