Switchgear Testing from Independent Testing Agency

At Independent Testing Agency, we specialize in both medium-voltage switchgear and low-voltage (480V) switchboard testing. Our acceptance and maintenance testing services are performed across all major manufacturers to help reduce unplanned outages, improve safety, and extend the lifespan of your electrical infrastructure.

Comprehensive Testing, Inspection & Cleaning

We begin with a thorough visual inspection of all insulating components to identify early signs of:

• Electrical distress
• Tracking
• Corona discharge
• Thermal heating

All enclosures are cleaned and inspected. Busbars, connections, and splices are examined for signs of overheating, and connections are re-torqued to ensure optimal performance and electrical integrity.

We Perform Critical Electrical Testing Procedures

We perform a series of advanced electrical tests to evaluate equipment health and prevent failure:

• Insulation Resistance Testing – Detects the presence of moisture, contamination, or insulation breakdown
• AC Overpotential Testing – Assesses the insulation’s dielectric strength
• Contact Resistance Testing – Identifies poor mating surfaces and pivot points, which can lead to localized heating and reduced current-carrying capacity

These tests provide actionable insight into the condition of your switchgear and allow for corrective action before failure occurs.

Why Switchgear Testing Matters

• Low insulation resistance can result in short circuits
• High contact resistance causes inefficient operation and localized heat damage
• Faulty grounding increases risk of electric shock and fire
• Lack of preventive maintenance leads to avoidable downtime and safety issues

A comprehensive switchgear and protective device maintenance program, including ground resistance testing, is essential to optimizing system reliability and safety. Regular testing and inspection reduce operational risk, improve system reliability, and help you comply with safety standards such as NETA and NFPA 70B.
