Your power systems need to run smoothly, safely, and without surprises, and we know that they're the backbone of your operation. Our transformer testing services are designed to help you avoid failures, meet compliance standards, and keep your team protected.
Whether you’re managing an industrial plant, commercial build, or a utility site, our testing team works with you to uncover risks, verify performance, and give you the peace of mind to keep moving forward, on time, and without compromise.

Types of Testing We Provide at JCL
Power distribution you can trust starts with testing you can rely on.
At JCL Energy, we know that every equipment you manage, whether it’s a padmount transformer, dry type transformer, or substation transformer, carries the weight of uptime, safety, and execution. Our power distribution equipment and transformer testing services are built to help you avoid costly downtime, catch issues before they grow, and assure your systems meet the highest standards so you can stay focused on the job ahead.
Transformer Electrical Testing
Electrical failures don’t wait for the right time; they happen fast and disrupt everything. That’s why JCL’s transformer testing detects hidden issues, verifies performance, and helps you stay ahead of outages.
• Voltage ratio & vector group verification
• Winding & insulation resistance testing
• Magnetizing current & balance checks
• Partial discharge, SFRA, Tan Delta
• Sweep Frequency & DIRANA analysis
Transformer Oil Testing
Oil testing is a window into transformer health. We analyze samples to spot early warning signs of insulation breakdown, contamination, or moisture issues.
• Dissolved Gas Analysis (DGA)
• Interfacial Tension & particle count
• Breakdown Voltage & moisture (PPM)
• Furan analysis for insulation
• Oil resistivity & Tan Delta
Transformer Breakers Testing
A breaker’s failure can shut down an entire system. Our breaker testing ensures protective equipment responds exactly when needed.
• Contact & insulation resistance
• Mechanical operation & withstand tests
• Timing tests for open/close response
• Integrity for low, medium & high-voltage
• Complete safety assessment
Transformer Relay Testing
Relays are your first responders. We make sure they react quickly, accurately, and in perfect sync with your system.
• Function testing (differential, overcurrent, etc.)
• Timing & coordination with breakers
• CT/PT accuracy verification
• Relay insulation testing
• Fault detection accuracy
