What is a Generator Paralleling Switchboard?

Every second of downtime in an industrial facility means a substantial amount of productivity and money lost. This is why it’s important for facilities to have redundant power systems set up in the event of a power emergency. One of the most common ways to build that crucial redundancy is paralleling generators. Having a system of parallel generators means facilities can have the backup power they need when their regular electrical source is cut off, but these systems require specific controls to keep them safe and effective. This is where a generator paralleling switchboard, also known as paralleling switchgear, comes into play.  

What is Paralleling?  

Basically, paralleling is the process of connecting two or more generators to provide double the amount of wattage. This connection of two electrical inputs means facilities have enough power to keep more than just basic systems functioning during a power outage. The benefits of connecting multiple generators include more flexibility, greater system reliability, and higher redundancy.  

How Does a Generator Paralleling Switchboard Support Paralleling? 

Paralleling switchgear is a crucial component that enables greater control when using paralleled generators in an electrical system,. These switchboards consist of breakers, meters, and control components including programmable logic controllers that ensure smooth and safe operation of generators running in tandem. Having paralleling switchboards is important because they provide a means of load management and synchronizing between generator systems to ensure consistency. At the same time, they also offer metering that technicians can use to make informed decisions about usage and maintenance.  

A paralleling switchboard can match the voltage and frequencies of multiple generators when they are connected to the same bus, ensuring consistent performance and safe operation. This equipment also ensures that load sharing is distributed evenly across all generators or proportionately to make sure no single generator is being tasked with more than it has been built to provide. Another critical function of paralleling switchgear is managing sequencing, automatically starting and stopping generators according to the current demand level. Finally, the presence of circuit breakers and protective relays means generator paralleling switchgear also protects the facility’s entire electrical infrastructure in the event of faults.
