A power supply may need to be flexible in order to handle temporary applications. Sometimes, power supplies must be installed on the job site or under a civil contracting agreement. A temporary or mobile substation is a good option if there is a high level of electricity consumption.
They can be quickly deployed and restored electrical service in an outage, or provide the additional electrical boost needed to complete construction projects at remote sites with heavy equipment. These substations can be used to provide temporary power, or an alternative power source for regular maintenance projects. Substations can be used for emergencies, new construction, and temporary service during maintenance.
These portable or mobile substations can be used to generate power on their own. They have a transformer and cooling equipment, switchgear, and metering.
The portable substation can be rolled onto a trailer and set up on the job site. Once it is installed, it will start generating power right away. Although the system comes fully equipped with all necessary equipment to generate power, it must be maintained and monitored. It takes approximately 4 hours to set up one of these systems.
You can choose from a variety of configurations for portable substations, including one with a rotating 360-degree bed that allows you to position and connect powerlines. Trailer-mounted switchgear systems are also available. These can be mounted with the truck and provide protection for the transformer. There are multiple ratings and voltages that can be used to power any project, depending on how big the trailer is.
When placing a substation, there are many factors to consider. If the substation is to be placed in public areas, temporary fencing must be used to surround it. Electrical clearances must also be observed. It is important to have an operational connection chart for all staff who work around or near the substation, as it has multiple voltage transformers. This will improve emergency response and shutdown.
