Its main business is the production, manufacture and sales of electrical equipment and testing instruments.
The principle of voltage boosting in test transformers is not mysterious; it is essentially the same as that of power transmission transformers in the electrical system—both rely on electromagnetic induction. However, it demands much higher requirements for voltage regulation range and output stabi
In power metering inspection work, there has been a persistent issue that plagues on-site personnel: when metering devices at substations or high-voltage users malfunction, troubleshooting errors requires power outages and circuit modifications, which is not only troublesome but also disrupts power
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
