BY BILL KHASHFE, London Hydro

According to an Ontario Electrical Safety Report, 35 percent of the province’s electrical-related fatalities in the past 10 years were attributed to power-line contact. Equipment specifications and electric utility construction plans within Ontario’s power industry, only a few decades ago, lacked regulation. Each utility developed its own policies.

Currently, the global economy has created a marketplace in which equipment is manufactured to various standards and, occasionally, with no standards at all. As a result, governments have started to step in to regulate the safety of equipment used...

How to guard utility personnel from shock hazards

Substations are active in fault clearance, and personnel working in and around them, as well as pedestrians passing in the vicinity, need to be protected. When a fault condition occurs, the grounding electrode (grid) must be sufficient to equalize potentials...
