Your Ultimate 2025 Guide: 5 Critical Faults a Sweep Frequency Response Analyzer Uncovers
Read moreAbstract A sweep frequency response analyzer (SFRA) provides a powerful and sensitive diagnostic method for assessing the mechanical and electrical integrity of power transformers. This technique functions by generating a low-voltage sinusoidal signal across a wide frequency spectrum and injecting it into one winding, while measuring the response signal at the other end. The resulting […]

The Ultimate 5-Step Guide to DC Winding Resistance Test
Read moreAbstract The DC winding resistance test is a fundamental diagnostic procedure for assessing the integrity of power and distribution transformers. This examination measures the direct current resistance of the transformer's windings, providing critical insights into the condition of the internal conductors and connections. By applying a stable DC current and measuring the resulting voltage drop, […]

7 Critical Reasons Your Substation Needs a CT/PT Analyzer in 2025
Read moreAbstract Instrument transformers, specifically Current Transformers (CTs) and Potential Transformers (PTs), are foundational components for the protection and monitoring of electrical power systems. The integrity of their performance directly impacts grid stability, equipment safety, and revenue metering. Traditional testing methodologies, often involving multiple separate devices and manual data interpretation, are increasingly viewed as time-consuming, prone […]

The 5-Step Guide to Choosing the Right CT PT Analyzer in 2025
Read moreAbstract The operational integrity of power systems is fundamentally dependent on the accuracy of instrument transformers. Current transformers (CTs) along with potential transformers (PTs) are crucial apparatuses that scale down high currents and voltages to safe, measurable levels for protection relays and metering equipment. A failure or inaccuracy in these components can lead to catastrophic […]
