LZZBW‑10 10kV Outdoor Current Transformer for Medium Voltage Substation

Model and its meaning

Summarize

Current transformer is essential for utilities and industrial facilities requiring precise monitoring of electrical parameters, Its efficient ability to measure current and voltage enables better energy management and resource optimization. Its protective relay function is crucial for protecting electrical equipment from potential overloads and faults, minimizing downtime and maintenance costs.

High measurement accuracy to meet measurement and monitoring needs. Current transformers offer excellent precision for applications requiring high accuracy, such as energy metering and power quality monitoring. They are classified according to standards into different accuracy levels (e.g., Class 0.2 and Class 0.5 for metering, and Class 1 and Class 3 for protection). Within the rated load and rated current range, they accurately reflect the magnitude and phase of the primary current, ensuring accurate energy metering (ensuring fair settlement between power suppliers and users) and reliable monitoring of power system operating status.
