Product Introduction:
The induced overvoltage withstand test of transformers and instrument transformers is an important test to ensure that the quality of transformers meets national standards. The longitudinal insulation induced overvoltage withstand test of transformer windings, including inter-turn, inter-layer, inter-section, and phase-to-phase insulation, is a crucial item in transformer insulation testing. Due to the special nature of longitudinal insulation testing, it is necessary to apply a multi-frequency power supply device to increase the test voltage between windings, thereby achieving the purpose of the withstand voltage test.
The induced overvoltage withstand test device is designed and manufactured by our company based on field experience and customer feedback to meet various customer needs. It is simple to operate, reliable in performance, and can effectively meet the requirements of induced overvoltage withstand tests for transformers and instrument transformers.
The output of the induced overvoltage withstand test device is a sine wave with low waveform distortion, and the waveform distortion rate is less than 3%. The entire multi-frequency induced overvoltage test set is compact in size, has good waveform, and stable output. The core component of the device - the variable frequency power supply - is controlled by a high-performance microprocessor, with a full Chinese menu display, featuring high automation, rapid and reliable protection, and a user-friendly interface. Please read this instruction manual carefully before use to avoid unnecessary damage to the test object and the test device due to misoperation.

Product Features:
1. The induced overvoltage withstand test device has protection functions such as overvoltage, overcurrent, zero-start, and flashover. The overvoltage and overcurrent protection values can be set according to user needs. When the test object flashes over, the flashover protection acts to protect the test object.
2. The entire induced overvoltage withstand test device is lightweight per component, making it convenient for field use.
3. The induced overvoltage withstand test device has automatic and manual modes, allowing users to flexibly choose based on site conditions to improve test speed.
4. It can store and remotely print data. The stored data numbers are numeric, making it easy for users to identify and search.
5. It adopts DSP platform technology, which makes it convenient to add or upgrade functions according to user needs, and also makes the human-machine interface more user-friendly.
