HAZARDS AROUND

While working live in the energized grid, presence of voltage around the workers requires special attention. However, live-line (live working) techniques are widely applied for decades, several accidents in the past prove that the level of safety must be improved to minimize the number and seriousness of injuries in the future.
In the high voltage grid, bare-hand method is a common technique for safe live work. In the surroundings of any energized equipment,...

Compatibility Issues with Generator-Backed Power Systems

Line-interactive uninterruptible power supply (UPS) systems play a vital role in maintaining seamless operation during power outages. Their integration with backup generators, however, can pose challenges regarding synchronization and power quality.

While both UPS systems and generators serve as safeguards against power disruptions, their integration isn't always seamless. Understanding these compatibility concerns is crucial for ensuring reliable backup power and avoiding damage to sensitive equipment.

Voltage and Frequency Stability

Generators, particularly smaller portable models, may not provide the same level of voltage and frequency stability as utility power. Line-interactive UPS units are designed to operate within a specific input voltage and frequency range. Wide fluctuations outside these tolerances can trigger the UPS to switch to battery frequently, draining reserves and potentially causing premature battery wear.

Synchronization Issues

When power from a generator is restored, there may be a phase shift or momentary mismatch...
