Difference between VLF tester and DC hipot tester
Read morethe difference between VLF tester and dc hipot tester: Both VLF testers and DC HiPot testers are used to assess the insulation integrity of electrical cables and equipment, but they operate using different principles and are suited for different applications. Here’s a breakdown of the key differences between the two: 1. Operating Principle: VLF Tester (Very Low Frequency Tester): […]

Transformer winding resistance test in the field Testing Commissioning
Read moreTransformer winding resistance tester helps identify potential issues like winding faults, poor connections, and other resistive losses that could lead to overheating or performance degradation. When you’re using a winding resistance tester, you’re typically looking to measure the DC resistance of the transformer windings at various taps or stages. This can help you detect issues like: 1. Winding […]

Some professional knowledge about SFRA
Read moreSFRA stands for Sweep Frequency Response Analysis, and it’s a diagnostic technique used primarily for testing the condition of transformers and other electrical equipment, such as shunt reactors, generators, and bushings. SFRA is used to detect mechanical deformations, winding movement, core displacements, and other potential faults that could affect the performance and safety of power […]

what’s the oil bdv tester is uesd for? and how to use?
Read morewhat’s the oil bdv tester is uesd for? An oil BDV (Breakdown Voltage) tester is used to measure the dielectric strength of insulating oils, typically in transformers and other electrical equipment. It determines how well the oil can withstand electrical stress without breaking down. A higher breakdown voltage indicates better insulating properties, which is crucial […]
