High Voltage Power Fruquency GTU Test Transformer

550 kV/GIS (Gas-Insulated Switchgear) units; dynamic AC withstand voltage test with switching loads of 1–2 A at a maximum voltage of 318 kV without partial discharge

1. it is suitable for test subjects with a maximum capacitance of ≤0.02 μF, a test frequency of 50 Hz, and a maximum output voltage of 350 kV.
2. Test high-voltage current I = 2πfCU_(test) = 2π × 50 × 0.02 × 10⁻⁶ × 318 × 10³ = 2 A

● Data such as voltage, current, time, status information, and prompts are displayed on a 27-inch LCD screen, providing clear and intuitive readings;

● Fully Chinese interface with simple and straightforward operation, suitable for a wide range of applications;

● Touchscreen operation; all functions can be preset in advance, enhancing the product's safety and reliability;

● Status alert function with fully Chinese guided operation;

● Alarm function: closing alarm with a 5-second buzzer alert; buzzer alarm for abnormal voltage signal acquisition;

● Emergency stop function: during automatic control, this function allows for an emergency stop of voltage increase or decrease at any point;

● Automatic timing function: during automatic control, when the voltage automatically rises to the set value, the device automatically starts timing; when the timer expires, the device automatically reduces the voltage and returns to zero;

● Manual control mode: This mode is similar to traditional electric voltage ramp-up/ramp-down methods, with ramp-up and ramp-down controlled by touch buttons. The device automatically detects upper and lower limit positions and provides high-voltage overvoltage protection, low-voltage current protection, and high-voltage overcurrent protection;

● Combines hardware and software anti-interference technologies to ensure stable performance and strong resistance to interference.
