The Importance of Testing Switchgear

 


Switchgear is an essential part of protecting both low- and high-voltage electrical systems from faulty and hazardous conditions. Without effective and reliable switchgear, electrical failures are more common and more dangerous. 

Electrical switchgear is important for several key reasons: 

  • Improves reliability of electrical systems - Properly functioning switchgear isolates faulty sections of the circuit, allowing power to flow uninterrupted. 
  • Enables a quicker response - Automated switchgear, like a relay and circuit breaker, will react quickly to a power surge or other type of electrical fault. Switchgear helps address the initial issue more quickly and safely than human intervention. 
  • Offers physical, on-site control - Switchgear also enables on-site control by engineers, technicians, and Field Evaluation Body (FEB) personnel. This allows qualified individuals to turn off a certain system during maintenance or upgrades, or direct power away from larger issues in the circuit. 

However, simply having switchgear in place is not enough. The switchgear must be up-to-date with all applicable industry standards and laws to ensure safety and continuous operation. Here are three reasons that testing switchgear is a necessary, and even helpful, undertaking. 


Testing ensures the equipment and facility are in compliance with applicable regulations

First and foremost, testing electrical switchgear is required to comply with electrical safety standards in all major consumer markets. Switchgear is an essential component of keeping offices, schools, businesses, residential complexes, and public spaces safe from dangerous electrical faults; as such, they are on the mandatory certification list in almost all regulatory schemes. 

In order for electrical switchgear to be compliant with applicable regulations, it must have an active certification from an approved regulatory body, a report from a Nationally Recognized Testing Laboratory (NRTL), or a successful field evaluation that is approved by the Authority Having Jurisdiction (AHJ). If a new building is constructed and it includes electrical switchgear, for example, it must meet one of those requirements. 

However, this is not only applicable for new construction. After retrofitting, expanding, or replacing switchgear (even partially, like replacing a segment), the switchgear must be deemed compliant in its new form and usage. For example, the original switchgear is UL Listed, but adding a tap invalidates the original listing. In these cases, a Field Evaluation may be the fastest and most cost-effective means of demonstrating and documenting the conformity of the switchgear to relevant standards—without going through the longer certification process for this one-off situation. 


Testing provides useful baselines for long-term maintenance

Electrical systems are powerful, complex, and quite costly to replace. A cohesive, long-term plan for compliance, upgrades, and maintenance—often referred to as system lifecycle management or asset management—can save significant time and money down the road. 

When the switchgear is tested, either at a testing laboratory or on-site by a qualified field evaluator, the ensuing report will provide a wealth of information and reference material. The report will list all of the relevant information about specific components, which is helpful when it’s time to upgrade, repair, or replace. It will also include all the details of the equipment’s performance, which helps form a realistic average and benchmarks for performance—all of which is important to a long-term monitoring and maintenance plan.
