What is the role of electronic transformers?
The main functions of electronic transformers are:
1. Transmit the current and voltage information of the primary side of the power system to the secondary and cooperate with measuring instruments and metering devices to measure the current, voltage and energy of the primary system.
2. When the power system fails, the transformer can correctly reflect the current and voltage waveforms in the fault state, and cooperate with the relay protection and automatic devices to form protection and automatic control of various faults in the power grid.
3. The usual measuring and protection devices cannot be directly connected to the high-voltage, high-current power circuit. The transformer electrically isolates the primary-side high-voltage equipment from the secondary-side equipment and system, thereby ensuring the safety of the secondary equipment and personal safety, and transforms the high voltage and large current on the primary side into low voltage and small current on the secondary side. Standardization of metering and relay protection.
