Siemens APT current transformer – the difference between the ratio on a current transformer and the ratio on a watt-hour meter
1. Differences in use
The conversion ratio of the current transformer is inconsistent with the transformation ratio of the ammeter, which will lead to the inability to use the displayed value of the ammeter directly, and the proportional conversion must be carried out;
If the transformer of ratio 5 is used on the meter of ratio 1, the secondary current of CT will generally exceed 1A, so that the transformer of 5 is used on a meter of 1 ratio. Than 1 ...

Siemens APT Relays – The difference between solid state relays and intermediate relays
First, the solid-state relay has no contacts and coils in the structure, which can be opened and closed at a high frequency and will not produce sparks, and has a long service life;
Second, the intermediate relay is generally only used for the control loop, and cannot work with load, and will make a "pop" sound when it is sucked in;

Siemens APT Relays – The action of high and low voltage relays and how to adjust the low voltage side
1. Disconnect the control power supply: Before making the low-voltage terminal contact adjustment, the control power supply should be disconnected first to avoid the current directly or indirectly passing through the relay contact, and avoid electric shock or damage to the relay.
2. Open the relay cover: Open the relay cover, you can see the inside of the relay.

Siemens APT transformer - the use, principle and selection of current transformer
The principle of the current transformer is based on the principle of electromagnetic induction. A current transformer is composed of a closed core and windings. Its primary side winding turns are very small, string in the line of the current that needs to be measured, so it often has all the current of the line flowing through, the number of turns of the secondary side winding is relatively large, and the series ...
