The most troublesome part of conducting dielectric loss testing in a substation is not the operation, but the interference - the 50Hz power frequency electromagnetic field generated by surrounding equipment penetrates into the measurement circuit, completely submerging the measurement signal that wa
There is a set of "series parallel pressure plates" on the HZ-109S panel, and many engineers who are using this instrument for the first time do not understand the function of this switch - if they choose the wrong one, either the current cannot be output or the required range cannot be re
Relay protection tester is a core tool in the field of relay protection, which can cost tens of thousands of yuan. Choosing the wrong one can be troublesome for several years. Clarify the several core dimensions that truly affect the user experience, and compare them to avoid making mistakes.First:
Many engineers have completed circuit breaker characteristic tests and know that the opening and closing time should meet the standards, but their understanding of the significance of synchronicity is not deep enough - they think that a few milliseconds of three-phase difference is not a big deal. I
Many engineers know to use instruments to measure on load tap changers, but they do not know how to interpret the test waveform when they see it. Understanding the switching principle is the foundation of understanding waveforms. Once this logic is explained clearly, waveform analysis becomes easy.S
