Ultra High Voltage (UHV) refers to electrical power transmission at extremely high voltages, typically above 800 kV for AC systems and above 600 kV for DC systems. It is used for long-distance power transmission to reduce energy losses and improve efficiency.

UPS (Uninterruptible Power Supply) is a backup power system that provides temporary electricity during outages or voltage fluctuations, protecting sensitive devices from damage or data loss. Types of UPS: - Offline (Standby) UPS: Activates only during power failure. - Line-Interactive UPS: Regulates voltage fluctuations with automatic voltage regulation (AVR). - Online (Double-Conversion) UPS: Provides continuous, clean power by always converting AC to DC and back to AC. UPS is essential for data centers, hospitals, and industrial applications to ensure continuous operation.
