Everything You Need to Know About Switchgear Servicing & Maintenance

The first step to switching gears is knowing what you need. switchgear servicing & maintenance can seem complex, but it doesn’t have to be. To help you out, we’ve compiled a list of 3 things that you need to know about switchgear servicing and maintenance:

1) A qualified electrician should do the work on your switchgear. This includes opening panels or enclosures, making connections or disconnections, inspecting for damage and defects in insulation, and testing equipment operation.

2) It’s not uncommon for electrical contractors to use an inductive current clamp meter (ICM), voltage drop test set (VDS), wire brush cleaner set, or thermometer when performing this type of service/maintenance task. These tools are used to help determine if there are any loose connections, overheated parts, or insulation damage.

3) The temperature of a switchgear unit’s enclosure is an essential factor when performing its servicing and maintenance, especially if it has a large amount of current flowing through it. A section can reach temperatures as high as 150 degrees Celsius (or 300 degrees Fahrenheit), which can cause severe burns to the skin in just seconds!

A qualified electrician should inspect these units at least twice per year, once in winter and once again in summer.


Switchgear units used for electric power distribution or generation need their enclosures inspected even more frequently than other types because they carry higher voltages that produce more excellent heat dissipation during operation.
