Next, this operation will be explained. Now, the primary terminal 5a,
When a primary circuit, that is, a power source is connected to 5b, primary terminal 5a → fuse 7a → connection terminal 3a → lead wire 202a → primary coil 202 → lead wire (not shown) → connection terminal 3b → fuse 7b → primary terminal 5
Current flows through the primary coil 202 due to the closed circuit b. At this time, an induced voltage is generated in the secondary coil 203 due to the main magnetic flux within the core 201, and the secondary terminals 8a,
An output voltage proportional to the voltage of the primary circuit is generated between 8b and 8b.

Generally, the primary coil 202 is connected to the secondary terminals 8a, 8
If the secondary coil 203 is burnt out due to a short circuit or poor insulation of the secondary coil 203, a problem occurs in which a large current flows through the primary circuit. For this reason, fuses 7a and 7b are installed to prevent the primary circuit and primary coil 20 from being connected in the event of the above phenomenon.
2, that is, it has a function of disconnecting it from the instrument transformer. However, the primary circuit on the power supply side has a separate disconnection device such as a fuse, and there are cases where a fuse is not necessary for the voltage transformer. In this case, fuses 7a, 7b and fuse grips 4a, 4b, 6
a, 6b are removed and the connection terminals 3a, 3b and the primary terminals 5a, 5b are connected with insulated wires, and the positions of the primary terminals 5a, 5b are used without changing depending on the presence or absence of fuses 7a, 7b. is common.
