Illuminating Decisions: EPRI Lights the Way for Modern Lighting Adoption

Facility managers and operators understand the critical role lighting plays in their daily operations. Accounting for roughly 30% of a commercial building's energy load, lighting significantly impacts energy consumption and associated maintenance costs. However, focusing solely on the initial fixture cost misses a crucial aspect of responsible lighting management – the long-term perspective.

Traditional Fault Detection Methods

Historically, generator protection relied on electromechanical relays and simple electronic devices that offered basic fault detection capabilities.

Electromechanical Relays

Electromechanical relays were the cornerstone of early fault detection systems, operating on physical principles to detect overcurrents, overvoltages, or other anomalies indicative of faults.

Limitations of Traditional Methods

While reliable within their operating parameters, these traditional systems had limitations in terms of speed, selectivity, and sensitivity to complex fault conditions, often leading to delayed or inaccurate fault...
