3Z03UM

3Z03UM is a type of current transformer (CT). It is mainly used to measure the current of electrical equipment in industrial environments and take necessary protective measures when the current is too large. It is widely applied in various fields such as power distribution, metering and protection for automatic power system controllers.

The main application fields of 3Z03UM are power generation, transmission, and distribution. It is frequently used for current measurement in transformer substations, high-voltage switchgears, and low-voltage distribution apparatus. Additionally, it can also be used for voltage measurement and power factor measurement in generator and transformer circuits. 3Z03UM can work with various components, such as current and voltage transformers, circuit breakers, current switches, relays, insulation monitoring devices, and capacitive voltage dividers.

The working principle of 3Z03UM is simple and effective. It is basically composed of two parts: a primary coil made of copper wire and a secondary coil made of fine copper wire. When a current flows through the primary coil, a magnetic field is created, which causes the current in the secondary coil to be proportional to that in the primary coil. This allows the user to measure the current in a circuit without needing to break it. Additionally, the 3Z03UM uses an open-loop system, which means that the current in the primary and secondary coils is constant regardless of fluctuations in the load, making it highly accurate and reliable.

In conclusion, 3Z03UM is an effective device for measuring current in industrial environments, and it is widely used in various fields such as power generation, transmission, and distribution. It consists of two coils connected in an open-loop system, and its working principle is based on the magnetic field created by the primary coil inducing a current in the secondary coil, allowing the user to measure the current in a circuit without interruption.
