Here we have described the details testing procedures of type test, routine tests and acceptance tests of different electrical equipment’s
First, we cut a 5m long sample of the stranded conductor. Then we fix the contact clamps for the measurement one meter apart from each other on the sample conductor. Then we use a Kelvin Double Bridge to measure the DC resistance of the conductor between the clamps. Also, we can use a micro-ohm meter … Read more
Power transformers are critical to electrical systems, and their failure can lead to major disruptions. Sweep Frequency Response Analysis (SFRA) is a powerful diagnostic tool used to detect mechanical and electrical issues inside a transformer before they cause serious problems. It helps identify winding movement, core displacement, insulation failure, and structural deformations by analyzing how … Read more
