■ Product Overview

The induction withstand voltage test of transformer and transformer is an important test to ensure the product quality meets the national standard. Transformer winding between turns, layers, sections and phase of the longitudinal insulation induction withstand voltage test, is an important item in the transformer insulation test. The longitudinal insulation test requires frequency doubling power supply device to apply test voltage and withstand voltage test.

■ Functional features

▲ The device adopts power electronics technology, and the internal core part uses frequency conversion regulator. Parameter preset, protection setting, frequency selection, voltage regulation and control, all adopt digital control technology. Built-in computer, 8 inch color LCD display, data storage can reach 3200 groups.

▲ Can preset 50Hz, 100Hz, 150Hz, 200Hz test frequency (optional), touch mode to adjust the voltage (step can be adjusted in real time, choose 1V, 2V, 5V, 10V), can realize the device multi-frequency test voltage output.

▲ External LC filter circuit to ensure waveform distortion rate within the range of indicators. External compensation inductor with tap to compensate the capacitive current of the tested equipment and improve the load capacity of the device.

▲ Small size, light weight, easy to carry, easy to high-power.

▲ Not only produces three times the frequency, but also produces 1, 2, 3, 4 times the frequency of the test voltage output.
