I. AC Series Excitation Test Transformer Product Overview
GYSB Light AC/DC High Voltage Test Transformer is a new type of high-voltage testing equipment. This series of products adopts a single-frame core structure, with the primary winding and high-voltage winding coaxially wound on the core, thereby reducing leakage flux and increasing coupling between windings. The overall structure is compact, with strong versatility and easy portability, suitable for on-site testing of insulation performance of various high-voltage electrical equipment in power systems and by power users. It is an essential test instrument for power equipment testing and preventive tests.
In addition to AC power frequency withstand voltage tests, if equipped with capacitors, silicon stacks, and high-voltage DC microammeters of the same voltage level and capacity, it can be assembled into a DC high-voltage test device to measure high-voltage DC leakage current.
II. AC/DC High Voltage Test Transformer? Operation Steps
1. Connect the leads according to the wiring schematic diagram, and reliably ground the transformer and control box;
2. Before the test, check whether the wiring at each part is in good contact, and check whether the voltage regulator of the control box is adjusted to the "zero" position;
3. Connect the power supply, the green indicator light turns on, press the start button, the red indicator light turns on, indicating that the transformer is energized and waiting for voltage increase;
4. Rotate the voltage regulator handle clockwise at a uniform speed to increase the voltage, and closely monitor the instrument indications and the condition of the test object;
5. After the test is completed, quickly reduce the voltage to zero, press the stop button, then cut off the power supply and disconnect the test leads.
