Description
Product Description
| Product name | Power factor correction for 11KV system |
| Model No. | STBB-4500/11 |
| Rated voltage | 11KV, 50Hz |
| Rated capacity | 4500Kvar, 3*1500Kvar steps |
| Exported to | Mali |
| Working principle | Power factor correction for 11KV system is used to improve power quality, through automatical computering, logical judgment and program setting to send control signal, control vacuum contactor switching and capacitor bank running automatically. |
| Features | 1. Enhance power quality of installations and improve electrical network efficiency, both resulting in considerable economical savings for end users. |
| 2. High quality discharge devices are installed inside the unit, and residual voltage can be reduced under 50V in 5 minutes when the unit is separated from power system. | |
| 3. Can be installed detuned filter reactor in series with reactance ratio from 0.5% to 13%, to limit inrush current and filter selective harmonics. | |
| 4. Install transfer switch with manual and automatic switch-on function. | |
| 5. Protection function: overvoltage, undervoltage, overcurrent and open delta protection. | |
| Service condition | 1. Ambient temperature: -10℃ ~ +40℃. |
| 2. Relative humidity: Less than 85%, non-condensation. | |
| 3. Altitude: Less than 1000m. (more than 1000m should be with special design.) | |
| 4. Installation site: Indoor service. Vertical inclination shall be less than 5 degree. No fire hazard, explossion risk, conductive dust, corrosive gas and strong vibration exist. |
