The current transformer is an instrument that converts the large current in the primary side circuit into a small current that can be measured by the secondary side ammeter. It is mainly used for current monitoring and measurement or measurement of electrical energy.   Introduces the monitoring and measurement of current: Current monitoring and measurement is divided into two forms, one is ammeter detection of current; the other is thermal overload protection measurement.   The wiring method for ammeter to detect current is as shown below: Current transformer circuit diagram The P1 terminal of the current transformer in the figure is connected to the ammeter A1, and the A2 terminal is connected in series with the P2 terminal of the transformer and is grounded.   How to short-circuit other unused transformers? As we all know, the secondary side of the current transformer must not be opened. Because the current transformer is a step-up transformer, in an open circuit state, high voltage will be generated on the secondary side, which may easily cause electric shock to the human body. Therefore, the secondary side must be short-circuited when not in use. The simplest method is to connect the P1 and P2 terminals directly with a 2.5mm wire.   How to replace P1 and P2 when they are reversely connected? When the P1 terminal is connected to the P2 terminal, just connect the P1 and P2 terminals back to their original positions.   Hemei Electronics is committed to the research and development, production and sales of amorphous, nanocrystalline and permalloy magnetic core products.
