Model and its meaning
Summarize
In the world of electricity metering, voltage transformers play a vital role by converting high voltage to low voltage. Since standard electricity meters are designed to operate at lower voltages, this conversion is crucial for accurately measuring electricity usage. By reducing the voltage, these transformers are able to provide precise readings, which are crucial for billing and energy management. The accuracy provided by voltage transformers not only benefits utility companies but also ensures that consumers pay fair electricity bills.
Normal service condition
Installation site: Indoor.
Ambient temperature: This voltage transformer is suitable for indoor installation and can operate in temperatures ranging from a maximum of 40℃ to a minimum of -5℃. The average daily temperature should not exceed 30℃. The atmospheric conditions in the installation environment should be free of severe pollution.
Atmospheric conditions: The surrounding air must be free of significant pollutants.

Structure and characteristics
This series of voltage transformers features a pillar-type design and is fully enclosed in epoxy resin casting, offering excellent resistance to pollution and moisture, making it suitable for use in tropical regions. These transformers require no special maintenance, requiring only regular surface cleaning. The transformer’s secondary terminals are equipped with a terminal box with holes on the front and side for convenient and secure wiring. Additionally, the baseplate is equipped with a grounding bolt and six mounting holes for easy installation.
