    Summarize

    One of the primary advantages of voltage transformers is their ability to provide highly accurate voltage measurements. Accurate measurements are crucial for effective power system monitoring, helping to detect anomalies and implement corrective measures. Voltage transformers ensure the reliability of the data they collect, which is crucial for maintaining the integrity of the power system. This accuracy not only improves operational efficiency but also enhances decision-making in system management and maintenance.

    Normal service condition

    The normal operating conditions of voltage transformers include the following aspects:

    Installation location: It should be installed indoors to avoid the impact of outdoor environment on the equipment.

    Ambient temperature: Maximum air temperature 40℃ ; The minimum temperature is -5℃ . The daily average temperature does not exceed 30℃ .

    Atmospheric conditions: There is no severe pollution in the atmosphere.
