High Voltage Instrument Transformer
Product Title
Product Details
The JLS-35KV high-voltage electric energy metering box mainly consists of two parts: a combined instrument transformer and a meter box. The combined instrument transformer is composed of two or three single-phase voltage transformers and current transformers, using No. 25 transformer oil as the insulating medium. The primary and secondary terminals are mounted on the panel with porcelain bushings. The meter box is installed on the side of the combined instrument transformer and consists of one active watt-hour meter and one reactive watt-hour meter, offering advantages such as high metering accuracy, light weight, convenient installation, and anti-tampering.
Included models: JLS-3 high-voltage electric energy metering box, JLS-6 high-voltage electric energy metering box, JLS-10 high-voltage electric energy metering box, JLS-35 high-voltage electric energy metering box.
This electric energy metering box is suitable for three-phase power networks with outdoor rated voltages of 6, 10, 35kV and a rated frequency of 50Hz.
