Utility Electrical Inspections

Preventive maintenance inspections are critical for ensuring the safety, reliability, and continuous performance of utility electrical systems. DDP Technology provides full-service inspection programs that identify developing issues early, protect infrastructure assets, and support regulatory compliance.

Inspection Scope

Utility electrical inspections encompass a wide range of activities including visual assessments, equipment testing, and verification of installation practices. The scope typically includes substations, transformers, poles, vault rooms, and other critical electrical assets.

Inspection Methods

Various methods are employed during utility electrical inspections to ensure thorough evaluation of assets. These include:
Infrared Thermography

To detect overheating components.

Ultrasonic Testing

To identify internal faults and partial discharges.

CO₂ Dry Ice Cleaning

For cleaning electrical apparatus without damage.

Visual Inspection

For identifying physical damage or wear.

GPS Mapping

To record asset locations using GIS systems.

Utility Pole Testing

To assess structural integrity of utility poles.

Compliance and Documentation

Our inspections verify that equipment and work practices meet utility standards and regulatory requirements, including guidelines from the Ontario Energy Board (OEB). Each inspection includes documentation of safety conditions, maintenance activities, and equipment labeling.

Asset Verification

We validate and update asset records to support accurate asset lifecycle planning. This includes pole numbering, equipment tagging, and confirming system configuration.

Reporting Procedures

Comprehensive inspection reports provide clear findings, high-resolution photos, test data, and recommended corrective actions. Weekly progress updates and field safety audits maintain transparency throughout the project.
