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,...

How to reduce electrical-related deaths and injuries to zero

BY JENIFER ROBERTSON, Electrical Safety Authority

Consider this scenario: An electrician is modifying an electrical circuit in a ceiling space at an educational institute. To perform the task, he de-energizes his specific circuit, but leaves the others in the same junction box energized.

While making the wiring modifications, the electrician makes incidental contact with a 347-volt, energized conductor with his right thumb and baby finger. He receives a shock.

Does this sound like a rarity? Well, it is not. In fact, this is a real-life incident that happened in Ontario—and it...

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.
