What You Need to Know about Oil-immersed Transformer
Oil-immersed power transformers have many benefits, particularly their efficient cooling capabilities. They are used in many industries and can be found at both electrical substations and power distribution centers. Read on to learn more about oil-filled transformers and how they may be useful to you.
People often ask :When will the transformer at Risk?
The dielectric insulating liquid contains vital information about the health of a transformer. Regardless of the type of liquid—transformer mineral oil, na
tural esters, or synthetic liquid—not knowing its condition could mean your transformer is at risk of failure (and you won’t see it coming!).
- What is the moisture level of the transformer’s insulating materials?
- Have dissolved combustible gases formed?
- What are the hydrogen gas concentrations of the liquid?
- What are the ratios of carbon dioxide or carbon monoxide?
- Has the percent weight of the oxidation inhibitor decreased?
There are several things to consider when trying to prevent transformer failure, including gas generation, oil breakdown, dielectric breakdown voltage, degree of polymerization, electrical stresses, chemical tests, and the list goes on. We can help you answer these questions and eliminate the guessing game when it comes to transformer reliability.

Transformer Uptime + Longer Life = Serious Savings
A well-maintained and serviced transformer can last over half a century—supplying all the uninterrupted power you need. There have even been a few in our care that have lasted over 100 years! While we can’t guarantee a century of uninterrupted service, we can help you optimize asset life. Major contributors to extending asset life are annual transformer liquid sampling, testing, and diagnostic analysis, which helps you achieve maximum uptime and reliability. The greater the reliability, the longer the life. The longer the life, the greater the savings.
Preventing downtime is much more cost-effective than fixing something after it breaks. A reactive approach will always cost organizations more because of the cost of downtime that occurs after an unplanned outage. In 2018, a Machine Metrics article cited a project by Aberdeen Research, saying, that 82 percent of companies have experienced unplanned downtime over the past three years, and that unplanned downtime can cost a company as much as $260,000 an hour. It’s not the cost of the asset that’s the issue—it’s the cost of downtime while you wait for the replacement to be installed.
Protect Mission-Critical Equipment with Transformer Oil Testing
Some transformers require close monitoring due to their condition, cost, scarcity or uniqueness, or the critical nature of the equipment they power. Nantong Dazheng offers a comprehensive range of tests that pinpoint faults and diagnose potential problems before they cause interruptions to operations. These tests will help you protect mission-critical equipment and maximize the life of your transformer.
