Its main business is the production, manufacture and sales of electrical equipment and testing instruments.
Many users ask before purchasing charging and discharging testing equipment: which batteries can this instrument test? Can it only be used for substations, or can communication base stations and industrial and mining enterprises also be used interchangeably? In fact, the reason why the HZCF-400 seri
The appendix of the HZSF-702 instruction manual specifically lists the requirements for measuring the moisture content of SF6 circuit breakers, which is the direct basis for determining whether the measurement results are qualified on site. Only by interpreting the content of this appendix clearly c
In partial discharge detection, the unit of "apparent discharge capacity" is picoku (pC), but the instrument initially measures the amplitude of the pulse voltage, not the amount of charge. To convert voltage readings into accurate picoku values, a specialized calibration must be performed
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
