Our transformer products are widely used in subways, charging stations, medical care, wind power generation and other fields. With stable quality, we escort the subway to run steadily; with precise measurement, we help the development of new energy fast charging; with medical safety in mind, we protect the accuracy of medical equipment data; with wind power as a companion, we escort the development of green energy. All fields create glory together, and transformers lead the future!

1. Medium-Voltage Switchgear (e.g., Drawout-Type Cabinets):
Instrument transformers (Current Transformers - CTs & Voltage Transformers - VTs) are integrated to measure electrical parameters, provide isolation, and enable protective relaying. They ensure safe monitoring and control of power flow while isolating secondary circuits from high voltages.
2. Low-Voltage Switchboards:
CTs are commonly used for energy metering, load monitoring, and protection functions. They step down high currents to standardized, measurable levels for meters and relays, facilitating efficient power management and fault detection.
Key Benefit: Enhances safety, accuracy, and reliability in electrical distribution systems.

Key Applications:
Utility Substations: Feeder protection, incoming/outgoing line control, and transformer protection.
Industrial Power Systems:Protecting and switching large motors, capacitor banks, and main distribution feeders.
Renewable Energy Plants:(e.g., Solar/Wind Farm Collector Substations) for connection and protection of distribution circuits.
Combination Advantage: This pairing provides a reliable, maintenance-friendly, and environmentally superior solution (vs. SF6 technology) for outdoor installation, offering precise fault detection and rapid, safe circuit interruption.

Transformers are essential components in EV charging stations, primarily serving two key functions:
1. Current Measurement (Current Transformers - CTS)
They accurately monitor current flow to ensure safe operation, enable precise billing, and provide real-time data for system management.
2. Voltage Transformation (Power Transformers)
They step down grid voltage to levels suitable for charging equipment, ensuring compatibility and electrical isolation for safety.
In summary, transformers enhance safety, accuracy, and efficiency in EV charging infrastructure.

Instrument transformers, including current transformers (CTs) and voltage transformers (VTs), are essential components in electrical substations. They serve two primary functions:
1. Measurement: They safely step down high currents and voltages to standardized, low levels that can be handled by measuring instruments (like ammeters and voltmeters) and energy meters. This allows for accurate monitoring of power flow.

2. Protection: They provide isolated and proportional signals to protective relays. These relays continuously monitor these signals. If they detect a fault (e.g., a short circuit or overload), they automatically trigger circuit breakers to disconnect the faulty section, protecting expensive equipment and ensuring system stability.
In short, instrument transformers are the "eyes" of the substation, enabling the safe, accurate, and reliable operation of the power system by monitoring and protecting it.
