Preventive Maintenance

Scheduled electrical maintenance that finds problems before they cause downtime.

Overview

Unplanned electrical failures are one of the most expensive causes of production downtime. Dena Electronics offers scheduled preventive maintenance programs built around your production calendar — infrared thermography of panels and switchgear, breaker exercise and trip testing, torque verification on bus and feeder connections, insulation resistance testing on motors, and full reporting with photos, thermal images and corrective-action recommendations.

Benefits

Infrared thermography identifies hot spots before failure
Breaker testing and torque verification per NETA guidelines
Motor insulation testing with trend reporting over time
Fixed-price annual programs tailored to your facility

Our Process

Consultation
We meet with your maintenance, engineering and operations leads to understand production goals, uptime targets and existing electrical infrastructure.
Site Assessment
Our team walks the plant to review loads, arc-flash labels, single-line drawings and access constraints before finalising the scope.
Planning & Design
We prepare drawings, load calculations, short-circuit studies where needed, and a phased execution plan that respects your production windows.
Installation
Qualified industrial electrical professionals execute the work to CEC and CSA Z462 standards, with lockout-tagout and full hot-work permits in place.
Testing & Commissioning
Insulation resistance, contact resistance, phase rotation, protective-relay and functional testing verify every circuit before energising.
Completion & Handover
As-built drawings, updated panel schedules, arc-flash labels and closeout documentation are delivered at project closeout.

Frequently Asked Questions

Can you support industrial projects?

Yes. Industrial scope, required trade qualifications, permits and project responsibilities can be reviewed during the proposal stage.

Do you carry the insurance our plant requires?

Project-specific insurance and documentation can be confirmed during the proposal process.

Can you work around our production schedule?

Absolutely. We routinely execute industrial work on nights, weekends and planned shutdown windows so production keeps running.

Do you handle arc-flash studies and labelling?

Yes — we coordinate with engineering firms for short-circuit and arc-flash studies and apply CSA Z462-compliant equipment labels as part of the deliverable.

What industries do you commonly serve?

Manufacturing plants, food and beverage processing, distribution centres, warehouses, sawmills, cannabis production, cold storage and light-industrial facilities.

Do you offer ongoing maintenance?

Maintenance programs can be scoped around the equipment, facility requirements and preferred service schedule.

How often should we do infrared thermography?

Most industrial facilities benefit from annual thermal scans of main switchgear and MCCs, with more frequent scans on critical or heavily loaded equipment.
