CT Ratio Testing In Bangla | Current Transformer Ratio Testing | সিটি রেশিও টেস্ট

Hello, friends I’m Zahid Rahman it’s an EEE campus presentation. Today I’m show CT ratio testing in bangla. Actually it’s a tutorial on current Ttransformer ratio testing. This video made on how to test of a unknown CT ratio. All of my dear friends it’s a great opportunity to clear your concept about CT ratio testing procedure. CT ratio is described as the ratio of primary current input to secondary current output at full load. For example, a CT with a ratio of 300:5 will produce 5 amps of secondary current when 300 amps flow through the primary. If the primary current changes, the secondary current output will change accordingly. For example, if 150 amps flow through a 300 amp rated primary the secondary current output will be 2.5 amps. Unlike the voltage or power transformer, the current transformer consists of only one or very few turns as its primary winding. This primary winding can be of either a single flat turn, a coil of heavy duty wire wrapped around the core or just a conductor or bus bar placed through a central hole. he ratio test is conducted to prove that the ratio of the CT is as specified, and to verify the ratio is correct at different taps of a multi tap CT. The turn's ratio is equivalent to the voltage ratio of potential transformers and can be expressed as follows. Ratio tests are performed by applying a suitable voltage (below saturation) to the secondary of the CT under test while the primary side voltage is measured to calculate the turns ratio from the expression above.
