Current Transformer (CT) - Types, Working and Applications

WebIn the example below, if the T.C is actually rated 480 – 120 volts, the transformer ratio is 4:1 (480 / 120 = 4). Applying a test voltage of 120 volts to the primary will result in a secondary voltage of 30 volts (120 / 4 = 30). If transformer is subtractive polarity, the voltmeter will read 90 volts (120 – 30 = 90). shrouded meaning in english

WebFeb 20, 2024 · Transformers are also used at several points in the power distribution systems, such as illustrated in Figure 23.10.2. Power is sent long distances at high voltages, because less current is required for a given amount of power, and this means less line loss, as was discussed previously. But high voltages pose greater hazards, so that ... WebCT ratio means the currant transformation ratio, here the CT contains Single primary current and dual secondary current output. The ratio 100/5 means If the CT primary carries 100 Amps then the output of the CT secondary will be 5 Amps. The dual 5-5 A means the first core used for protection and second core used for metering purpose.
