This manual describes the LQG-0.5 series current transformer, its intended applications, and compliance with GB1208‑2006. It outlines the operating principle, where the primary current induces a proportional secondary current through a magnetic core.
Technical data such as rated voltage, frequency, primary and secondary currents, accuracy class, burden, and physical dimensions are listed. Installation instructions cover vertical or horizontal mounting with bolts, and safety precautions address fire, moisture, and proper placement. This manual is written in Chinese.
| Rated voltage | 0.5 kV |
|---|---|
| Rated frequency | 50 Hz |
| Rated primary current | 10 A – 75 A (selectable) |
| Rated secondary current | 5 A |
| Accuracy class | 0.2, 0.5, 1.0 |
| Rated burden | 2.5 VA, 5.0 VA, 10 VA |
| Power factor (secondary) | 0.8 (lag) |
The transformer can be ordered with primary currents from 10 A up to 75 A.
It can be mounted vertically or horizontally and fixed to a bracket with bolts.
