Product Specification

Voltage Regulation

Automatic Adjustment: OLTCs enable precise and continuous voltage adjustments to maintain output voltage within specified limits despite load or input voltage variations.
Tap Range: Typically ±10% of the rated voltage, with fine steps of 1.25% or 2.5%.

Operation Mechanism
On-Load Operation: Tap changes occur without de-energizing the transformer or interrupting the load.
Arcing Control: Special diverter switches and resistor or reactor assemblies minimize arcing during tap changes, ensuring smooth transitions.
Cooling Options
Available with cooling systems like ONAN, ONAF, OFAF, or ODAF, depending on the load and application.
Applications
Power Transmission: High-voltage substations where precise voltage regulation is critical.
Industries: Steel, cement, and manufacturing plants requiring stable voltage for heavy machinery.
Utilities: Distribution networks with fluctuating load conditions.
Key Components
Tap Changer Mechanism: Installed in a separate compartment for easy maintenance.
Diverter Switch: Handles the load current during tap changes to prevent interruptions.
Control Panel: Provides automatic or manual control of the tap changer.
Monitoring Systems: Includes devices for temperature, oil level, and tap position monitoring.
