Advanced High-Precision dga analysis of transformer oil Solutions for Finland

Market Development History

During the late 20th century, electrical testing in Finland relied heavily on manual analog meters. The primary focus was on reactive maintenance, where components were replaced only after failure. Basic insulation tests were the norm, with limited capability for detecting subtle hipot leakage current trends.

Between 2000 and 2015, the industry shifted toward digitalization. The introduction of microprocessor-based testers allowed for more precise fault localization. This era saw the rise of specialized equipment capable of performing a comprehensive dga analysis of transformer oil, moving the industry from "find and fix" to "predict and prevent."

Since 2016, the integration of IoT and cloud computing has transformed Finnish grid management. Modern testers now synchronize data in real-time, allowing engineers to monitor the health of high-voltage assets remotely, significantly reducing the need for hazardous on-site manual testing in winter conditions.
