The relay protection tester under UHV power can help many power workers conduct various power tests more conveniently.
The relay protection tester is independent of two sets of DC voltages and can output simultaneously when connected. It can be used as a protective power supply without the need to set or adjust software. Today, we will introduce the structure of the relay protection tester in detail.
1. Adopting special designs from the railway industry. The relay protection tester adopts a ferroelectric differential testing menu, which operates based on the differential protection of ferroelectric traction transformers. According to transformer differential protection, the relay protection tester has characteristics such as proportional braking, magnetic assistance, and harmonic braking.
2. There are many touchpoints, and the software functions are very powerful. The relay protection tester has eight optical inputs and four optical outputs. The input contacts are compatible with both empty contacts and potential contacts, and can be intelligently recognized.
3. There are over 20 buttons on the panel of the relay protection tester, which are operated by a large LCD screen. All interfaces are displayed in Chinese, which can complete most of the on-site testing work. At the same time, it is also very convenient to complete the testing of protective devices from foreign manufacturers.
4. The relay protection tester can be placed vertically or horizontally. It can also be operated through external computer devices. The test results can be automatically organized and recorded as a test report for your reference. Of course, you can also use a mobile USB drive to save and then transfer it to an external device for editing and printing processing.
It can be seen that the relay protection tester is a very advanced and intelligent device. In addition to the above characteristics, the software upgrade operation is also very fast and simple. We can upgrade directly from a USB flash drive or download from an external computer without any hardware changes.
