Explanation: When measuring AC current, if the input current is greater than 5A, an electrical transformer CT must be connected to the input terminal. CT
The secondary transformation ratio current is 5A.
When measuring AC voltage, if the input voltage is greater than 1000V, a voltage transformer PT must be connected to the input terminal. The secondary transformation ratio voltage of PT is 100V. |
|
| When measuring with a DC ammeter, if the input current is greater than 5A, a current divider must be connected to the input terminal, and the secondary voltage ratio of the divider is 75mV. |
