Switchgear upgrades

Switchgear and distribution upgrades for Edmonton-area plants and large buildings: replacement, extension, retrofit breakers and planned outages with full documentation.

Why switchgear gets upgraded

Switchgear is the heart of a plant's power system. It takes the incoming supply and splits it into feeders for everything else. Most of it is built to last decades, but at some point it needs attention.

The usual triggers are:

• Breakers that are obsolete, with parts no longer made.
• A plant expansion that needs more capacity or new feeders.
• Test results showing worn contacts, failing insulation or slow trip times.
• Safety concerns, such as high arc flash energy at the existing equipment.
• Insurance or corporate standards requiring modern protection.

Replace, extend or retrofit?

A full replacement is not always necessary. We look at the condition of the bus, enclosure and breakers and help you weigh the options:

Upgrades to switchgear usually involve an engineer for protection coordination and, depending on scope, stamped drawings. We work with your engineer or arrange one.

Planning the outage

Switchgear work almost always means a shutdown of some or all of a site. Good planning shrinks it. Before the outage, we:

• Confirm the sequence with the utility if the service has to be disconnected.
• Pre-build and pre-test new equipment where possible.
• Arrange temporary generator power for critical loads if needed.
• Walk the plan with your operations team so everyone knows the timeline.

Testing, labelling and records

Before anything is energized, new and modified equipment is tested: insulation resistance, connection torque, protection settings and breaker operation. We then label equipment, including arc flash labels where a study has been done, and update the single-line drawing.

Cost depends on the size and voltage of the equipment, how much is replaced, lead times for new gear, engineering, outage scheduling and any temporary power. Lead times on switchgear can be long, so early planning matters as much as the budget.

Getting the most from existing gear

Not every concern means new equipment. Sometimes the right answer is to extend the life of what you have while you plan and budget for replacement. Options we often discuss include:

• A full inspection and cleaning during the next shutdown, with connections torqued and insulation checked.
• Testing breakers to confirm they still trip as they should.
• Thermal scanning under load between shutdowns to catch hot spots early.
• Stocking critical spare parts while they are still available.
• Moving non-critical loads to free up a feeder for new equipment.

We will give you a straight assessment of the equipment's condition and how long it is reasonable to keep it running. That way an upgrade happens because you planned it, not because a failure forced it. Regular industrial maintenance is the best way to keep that picture current.
