Switchgear is a broad term used to describe the various switching devices that control, protect and isolate power systems. Specifically, switchgear can accommodate higher voltages up to 350 kV. Depending on the electrical system's layout and design, switchgear can encompass components such as switches, fuses, circuit breakers, lightning arrestors, relays and isolators.

A switchboard works in tandem with switchgear to optimize the protection and coordination of the electrical system. It consists of panels or frames designed to hold devices like switches and indicators. It also contains control and monitoring devices and busbars to distribute the incoming power supply. Most switchboards accommodate lower voltages under 600V. 

A comprehensive switchboard and switchgear maintenance and testing process consists of the following steps:

• Conducting an infrared inspection to identify issues before they cause a partial or complete power outage
• Exercising the circuit breakers to keep contacts clean and allow operating mechanisms to move freely
• Ensuring compliance with NETA, NFPA 70E and other regulatory requirements
• Conducting a short-circuit analysis and time current correlation study to minimize the risk of catastrophic damage to the equipment and surrounding area
• Performing routine maintenance processes like lubricating, cleaning, inspecting and tightening the various components
• Tracking maintenance testing data to project the equipment's life expectancy and anticipate future service requirements
• Upgrading absolute circuit breakers and other outdated parts and components
• Reconditioning parts on-site or in a fully equipped repair shop as needed

Panel Board Testing and Service

Panel boards are standard equipment in substations and many other industrial applications. They typically contain the secondary devices found in electrical systems, including control switches, measurement elements and signaling and secondary protection devices. Panel board testing can occur during manufacturing, commissioning and preventative maintenance. It covers wiring, protective scheme testing, dielectric resistance, polarity continuity and other crucial areas. 

The various panel board testing and service objectives include ensuring the effectiveness of all secondary protections to uncover reliability deficiencies before they lead to malfunctions. Testing can also verify that all wiring and signals are functioning properly.
