Uninterruptible Power Supply (UPS) systems play a crucial role in ensuring the continuous operation of electrical equipment by providing backup power during outages and protecting against power quality issues. There are three main types of UPS systems: Offline, Line-Interactive, and Online. Each type has distinct features suited for different applications.
Voltage regulation in transformers is critical to ensuring stable and efficient operation in electrical power systems. Variations in load or supply voltage can lead to deviations from the desired voltage levels, potentially impacting the reliability and performance of equipment and infrastructure. Two primary techniques for regulating transformer voltage are On-Load Tap Changers (OLTC) and Off-Load Tap Changers (Off-Load Options).
