10kV On-Load Capacity and Voltage Regulating Oil-Immersed Power Transformers Overview
The on-load capacity and voltage regulating oil-immersed transformer is designed for 10kV distribution areas up to 630kVA. It provides automatic capacity and voltage regulation, distribution monitoring, and wireless remote control.

Product Features
-
Automatic Voltage Regulation: The transformer automatically regulates voltage in response to load fluctuations, improving power quality, extending equipment service life, and ensuring voltage compliance during peak and off-peak periods.
-
Automatic Capacity Regulation: The transformer automatically adjusts capacity according to load demand. During low-load periods, it operates at the low-capacity setting, reducing no load active loss to less than one third and reactive power demand to one tenth of those at high capacity.
-
Distribution Monitoring and Wireless Remote Control: Wi-Fi, GSM, and GPRS communication options enable real-time monitoring, remote control, and parameter viewing/setting for automated distribution network operation.
-
Maintenance-Free Design: Maintenance-free throughout the service life, providing convenient and reliable operation.

Expected Benefits of Capacity and Voltage Regulating Transformers
Improved Voltage Quality
Automatic on-load voltage regulation compensates for line voltage drops and load fluctuations, reducing overvoltage and undervoltage risks while improving voltage compliance and power quality.

Reduced No-Load Loss
Automatic capacity regulation enables the transformer to operate at a lower capacity during no-load and light-load periods, significantly reducing no-load loss and improving energy efficiency.

Improved Operating Safety
Capacity regulation helps meet seasonal and peak load demands while reducing no-load loss during low-load periods, supporting safe and efficient transformer operation.
