Its main business is the production, manufacture and sales of electrical equipment and testing instruments.
When performing high-voltage tests on large cross-section, long-distance cables, the issue often lies not with insufficient voltage from power frequency equipment but with its capacity and size making it difficult to handle on-site. Cables can be equivalently modeled as a large capacitance, which ge
When measuring with an insulation resistance tester, the insulation resistance value does not immediately stabilize at a certain number, but gradually increases from small to large over time - this process is called the "absorption process", which leads to an important parameter for measur
Understanding the measurement principle is essential to comprehend why HZ2611 supports both the two watt meter method and the three watt meter method, as well as why temperature calibration is necessary. By explaining the principles clearly, on-site operations are no longer mechanically following th
The discharge parameter setup interface of HZFD-200 includes over a dozen parameter items. Only by understanding the meaning and setting logic of each parameter can the test be conducted according to the regulations and ensure valid data.Basic information parametersMachine Room Number (0001～9999):
The determination of freezing point sounds simple—cool the liquid and observe when it begins to freeze. However, the SH/T 0090 method for measuring freezing point is far more complex. It does not measure the "temperature at which freezing begins," but rather a more physically meaningful p
