6 Essential Tests for Your Current Transformer Tester: A 2025 Practical Guide
Read moreAbstract The operational integrity of electrical power systems is fundamentally reliant on the precise and reliable performance of current transformers (CTs). These instruments serve as the sensory apparatus of the grid, providing critical data for metering, control, and protective relaying. A failure or inaccuracy in a CT can precipitate cascading failures, lead to significant financial […]

A Practical Guide to Sweep Frequency Response Analysis: 5 Steps to Detect Transformer Faults Early
Read moreAbstract Sweep Frequency Response Analysis (SFRA) is a non-invasive diagnostic method used to assess the mechanical integrity of power transformers. By injecting a low-voltage sinusoidal signal across a wide frequency spectrum and measuring the response, this technique generates a unique frequency-dependent signature for the transformer's active part, including its windings and core. This signature serves […]

Your 2025 Buyer’s Guide: 5 Essential Features in a TTR Tester to Avoid Costly Transformer Failures
Read moreAbstract The transformer turns ratio (TTR) test is a fundamental diagnostic procedure for assessing the health of a transformer's windings and magnetic core. This examination evaluates the ratio of the number of turns in the primary winding to that of the secondary winding, a parameter determined during manufacturing. Deviations from the nameplate ratio can indicate […]
