How to Read CT Current Transformer Nameplate Details

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 ... 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). fm radio station frequencies uk
