Jszwk-10kv 10000√ 3/100√ 3/100V Outdoor Anti-Resonance Three-Phase Dry-Type Voltage Transformer

The high voltage is converted into a standard secondary voltage of 100V or lower according to a proportional relationship, which is used for protection, metering and instrumentation devices. At the same time, the use of voltage transformers can isolate high voltages from electrical workers. Although the voltage transformer is also a device that works according to the principle of electromagnetic induction, its electromagnetic structure relationship is exactly opposite to that of the current transformer. The secondary circuit of the voltage transformer is a high-impedance circuit, and the magnitude of the secondary current is determined by the impedance of the circuit. When the secondary load impedance decreases, the secondary current increases, so that the primary current automatically increases a component to satisfy the electromagnetic balance relationship between the primary and secondary sides. It can be said that the voltage transformer is a special transformer with limited structure and use form. Simply put, it is the “detection element”.
