What is the process for performing a hot tap in a substation?

The process of performing a hot tap involves connecting to an active pipeline or circuit without interrupting service. This technique is crucial in substations where maintaining power supply is vital, allowing for system maintenance or upgrades while minimizing downtime.

Hot tapping requires specialized equipment and safety procedures to manage the connection safely, ensuring that the existing system remains operational during the process. This method is commonly used in various utilities, including water, gas, and electrical systems, to add new sections of piping or make modifications without incurring the costs and disruptions associated with service interruptions.

In contrast, shutting down the circuit before making connections would negate the purpose of a hot tap, as this method specifically aims to maintain operations. Similarly, stating that standard tools can be used without specialized equipment overlooks the safety and technical requirements necessary for effectively conducting a hot tap. Lastly, performing maintenance on the pipeline before connecting is not a part of the hot tap process, as the connection is intended to be made while keeping the pipeline operational.
