Whether it is designing the power system, daily operation, or post maintenance, understanding its functions, advantages, and application scenarios is essential for smooth work.

Working conditions

Welcome (Wenzhou) Electric Co., Ltd.'s JDZX11 voltage transformer. To ensure its stable and problem free operation, it is important to pay close attention to the following usage conditions and precautions:
1.Environmental requirements for use
Altitude: The maximum height cannot exceed 1500 meters. If used in high-altitude areas, the specific altitude must be specified in advance when placing an order;
Environmental temperature: It is commonly used between -5 ℃ and 40 ℃. If there are special temperature requirements, they must also be clearly noted in the order;
Relative humidity: The humidity should not exceed 85%, as excessively humid environments can easily affect insulation;
Installation site: Keep away from gases, vapors, chemical deposits, dust and dirt that can severely corrode the insulation, and avoid flammable and explosive media. The site should also avoid severe vibrations and bumps, otherwise it may damage the equipment.
2.Precautions for use
When a current is passed through the primary side of a current transformer, the secondary winding must not be open circuited! Once an open circuit occurs, it will generate high voltage, which not only affects product performance but may also pose safety risks;
The secondary winding of the voltage transformer must not be short circuited! Short circuit will directly burn out the transformer, causing equipment failure;
The repeated power frequency withstand voltage test of a winding must be conducted under the condition of 80% of the specified test voltage, without overvoltage testing to avoid damaging the insulation.
