GYSB Series AC Series-Excited Test Transformer
Darui Electric recommends for you:
I. AC Series-Excited Test Transformer Product Overview
AC Series-Excited Test Transformer is a new type of high-voltage testing equipment. This series of products adopts a single-frame core-type iron core structure, with the primary winding and high-voltage winding coaxially wound on the iron core, thereby reducing leakage flux and increasing coupling between windings. The overall structure of the product is compact, with strong versatility, and is easy to use and carry. It is suitable for power systems and power users to test the insulation performance of various high-voltage electrical equipment on site, and is an essential test instrument for power equipment testing and preventive tests.
AC Series-Excited Test Transformer can not only be used for AC power frequency withstand voltage tests, but 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 Series-Excited Test Transformer Operating Steps
1. Connect the leads according to the wiring schematic diagram, and reliably ground the transformer and control box;
2. Before testing, check whether the connections at each part are 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 boosting;
4. Rotate the voltage regulator handle clockwise at a uniform speed to boost 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 and press the stop
