Web25 de fev. de 2024 · The value of the resistance is calculated to be 288 ohms and the current in the resistance is 0.833 amps. In contemplating an open-circuit test at 480 V and 100 Hz, it is assumed that the current and level of magnetic flux will be unchanged since the ratio of voltage to frequency is unchanged. WebMost current transformers have a the standard secondary rating of 5 amps with the primary and secondary currents being expressed as a ratio such as 100/5. This means that the primary current is 20 times greater than the secondary current so when 100 amps is flowing in the primary conductor it will result in 5 amps flowing in the secondary winding. how do pre tax deductions work
