Customised Bsvr Feeder Transformer for Efficient Power Supply

An on-load tap changer is a mechanism installed in power transformers that allows voltage regulation while the transformer remains energized and supplying load, without any interruption to power supply. Its primary role is to maintain a stable output voltage despite variations in input voltage or load conditions.

SVR (Feeder Automatic Voltage Regulator) is an oil-immersed on-load tap-changing transformer series-installed in 6/10/35kV distribution feeders. It continuously tracks line voltage and automatically adjusts the on-load tap-changer position to regulate the transformation ratio, stabilizing the output voltage within the qualified range without supply interruption. Primarily used for voltage-drop compensation at the mid-to-rear section of radial feeders and voltage stabilization at substation outgo

The following information is required at ordering: 1. Model and rated capacity (e.g., BSVR-5000/10); 2. Rated voltage and regulation range; 3. Connection group (default Ya0); 4. Tap positions (7 or 9); 6. Transformer oil grade (25# or 45#, selected per minimum ambient temperature); 7. GPRS remote communication module (optional); 8. Special environmental conditions (high altitude, heavy pollution, extreme low temperature, etc.).

Radial distribution feeders (compensate line voltage drop), Renewable-integrated feeders (suppress over-voltage from reverse power flow), Substation outgoing feeders (stabilize busbar voltage), and Industry sectors including urban/rural grids, oilfields, coal mining, chemicals, metallurgy, and railway tunnel voltage boosting.
