The VLF hipot tester under Wuhan UHV can help many power workers conduct various power tests more conveniently.

1. Introduction

In the field of electrical equipment maintenance and testing, the VLF high voltage generator is widely used in various scenarios due to its high efficiency, energy saving, and easy operation. This article will demonstrate its performance in practical applications through several typical cases.

2、 Application Cases

Insulation testing of power cables

A certain power company decided to use VLF high voltage generator for regular maintenance of its 35kV cross-linked polyethylene insulated cable. Compared with traditional power frequency withstand voltage testing equipment, it not only shortens the testing time, but also greatly reduces power consumption and improves work efficiency.

Insulation testing of generators and motors

A large power plant introduced the VLF high-voltage generator during regular maintenance of one of its high-capacity generators. By using VLF equipment, not only has the testing time significantly shortened, but power consumption has also been reduced. Additionally, due to the small size and light weight of the equipment, on-site operation is more convenient.

Substation equipment maintenance

A certain substation selected VLF high voltage generator for regular insulation testing of multiple transformers in the station. Compared to traditional power frequency withstand voltage testing equipment, VLF equipment is not only smaller in size and lighter in weight, making it easy to carry to different testing points, but also easier to operate, greatly improving work efficiency.

3、 Summary of Practical Experience

Reasonable selection

Select the appropriate equipment model and output frequency based on specific testing requirements and technical parameters.

Standard operation

During the testing process, strictly follow the operating procedures to ensure the accuracy of the test results.

Timely maintenance

Regularly inspect and maintain the equipment to ensure its normal operation.
