Online Condition Monitoring

Prevent Transformer Failures Before They Happen

Real-time Dissolved Gas Analysis (DGA) monitoring that detects critical faults early, minimizes downtime, and extends equipment life.

Continuous Monitoring Backed by Expert Diagnostics

Around-the-clock transformer monitoring is only as valuable as the expertise behind it. SDMyers combines Guardian Monitoring® — our continuous gas monitoring solution — with proactive diagnostic analysis. This combination delivers exponentially more data than routine oil testing, with engineers who review flagged data, distinguish real threats from normal variations, and provide clear, actionable guidance when it matters most.

When connected to Transformer Dashboard®, your monitoring data becomes a living diagnostic record — with trend analysis, predictive insights, and expert recommendations that transform data into decisions.

Why Routine Oil Testing Isn't Enough

Transformer failures don't announce themselves — they develop gradually. Between routine oil samples, critical faults can emerge and escalate undetected. By the time your next scheduled test reveals the problem, you may already be facing emergency repairs, unplanned downtime, or catastrophic failure.

Your operation depends on knowing what's happening inside your transformers right now, not weeks from now when the next sample comes back.

The Transformer Monitoring Process

01

Detect

All transformer monitors deliver data accurately, exceeding industry standards, measuring gas levels in real time, 24/7.

02

Analyze

Data flows automatically to your Transformer Dashboard® and our engineering team. Algorithms flag any deviations from normal patterns.

03

Diagnose

Our engineers review flagged data and determine whether action is needed. You receive clear recommendations only when there's a genuine threat — no false alarms.

04

Act

Armed with detailed data and expert insight, you'll know exactly what steps to take to maintain operations with minimal downtime.

Choose the Right Monitor for Your Asset

Single-Gas Monitors

Single-gas monitors deliver a single data point that can provide an early warning for many kinds of incipient faults.

Five-Gas Monitors

Five-gas monitors provide the data required to remotely diagnose faults.

Nine-Gas Monitors

Nine-gas monitors are able to provide a complete DGA profile of the transformer, which allows even more detailed and precise information on fault conditions at an early stage.

SDMyers Guardian Dissolved Gas Analysis (DGA) Monitors

At the heart of your transformer are the DGA monitors that tell you exactly what is going on with your transformer’s health. Learn more about gas monitors and their capabilities.

Guardian Monitor Types Overview

The 3 types of gas monitors in a nutshell.

 

Transformer Monitors: One Size Does Not Fit All

The choice between monitoring systems is not one of “good/better/best.” Rather, it is a choice of which monitor fits the specific needs of your equipment, your operation, and your company’s mission... and one that should be made on a transformer-by-transformer basis.

Transformer Dashboard®: Guardian Monitoring

The online monitoring functionality on Transformer Dashboard allows users to view graphs, diagnostic tools, and “at-a-glance” recommendations.

What Are The Benefits Of Remote Fault-Gas Monitoring?

Online monitors help you stay on top of your transformer's health and make more informed decisions to ultimately keep your transformer running reliably for longer.

What Is DGA Testing?

DGA testing is one of the diagnostic tests we can run on dielectric fluid in a power transformer. DGA stands for Dissolved Gas Analysis — it tells you what's going on in the dielectric fluid.
