On-Load Tap-Changer (OLTC)
 |
An On-Load Tap-Changer (OLTC) transformer is a crucial component in power distribution systems. It allows for the regulation of a transformer’s output voltage without interrupting the power supply. This function is vital for ensuring a stable and reliable power supply, particularly during fluctuations in demand or system disturbances.
- Rated power (kVA): 160, 250, 400, 630, 800, 1000
- Primary rated voltage (kV): 6.3 / 10.5 / 15.75 / 21
- Secondary rated voltage (V): 400, 410, 420
- On-load voltage regulation: ± 4 x 2.5%
- Winding connection group: Dyn5, Dyn11
- Short-circuit voltage: 4%, 4.5%, or 6%
- No-load and load losses: Compliant with EU ECO Directive Tier 2
