Model and its meaning
Summarize
Beyond their core functions, voltage transformers also facilitate the implementation of automation and remote monitoring systems. By combining voltage transformers with advanced monitoring technologies, operators can remotely collect data, enabling real-time analysis and decision-making. This capability not only simplifies operations but also reduces the costs associated with high-voltage measurement equipment. Furthermore, some voltage transformers offer multiple functions, including additional features such as frequency and phase measurement. This integration provides a comprehensive monitoring solution, offering valuable insights into power system performance.
Normal service condition
Installation site: Indoor
Ambient temperature: The maximum temperature is 40℃ , the minimum temperature is -5℃ , and the daily average temperature does not exceed 30℃ .
Atmospheric conditions: Ensure that there is no serious pollution in the atmosphere to avoid affecting the insulation performance and working stability of the equipment.
When the above conditions are met, the voltage transformer can operate normally and safely.

Structure and characteristics
This series of voltage transformers adopt a pillar structure and are fully enclosed with epoxy resin by epoxy casting. They are resistant to pollution and moisture and are also suitable for use in tropical regions. The transformers do not require special maintenance; only regular cleaning of surface dirt is needed. Terminal boxes are installed at the secondary output terminals of the transformers. There is one hole on the front and one on the side of the terminal box to cooperate with the output terminals for leadout wiring, which is safe and reliable. There are grounding bolts and six installation holes for installation on the product base plate.
