The transmission and distribution industry’s foremost
challenge is to provide reliable, quality power. In
today’s electronics-oriented culture, it is virtually
impossible for a power loss or power quality
disturbance to go unnoticed, and the risks
to the utility are great:
• Power quality disturbances cause equipment
damage and blackouts
• Improper power factor control sacrifices energy
efficiency
• Unreliable electric service reduces customer satisfaction
and affects rates that T&D utilities can charge
Power delivery utilities must operate safely and with
minimal impact on the population and environment
even as they adapt to growing populations and
expanding businesses in their service area. Smart
Grid initiatives target improvements in reliability
and efficiency. For example, new regulations and
recommendations designed to reduce peak demand
and control load flow are moving the industry toward
greater energy efficiency. Enabling monitoring and
control capabilities enhances energy efficiency and
system reliability, including distribution automation
volt/VAR control, fault detection, overcurrent
protection and demand-reduction programs.

eliminates the need to replace FCIs as load changes
• Temporary fault detection option to help locate
nuisance temporary faults
Current-Limiting Fuses
• Greatly reduce energy let-through, minimizing the risk
of catastrophic failures
• Interrupting capabilities up to 50,000A
Capacitor Switches
• Vacuum interruption and solid-dielectric insulation
translate into maintenance-free and environmentally
friendly designs — no oil, no gas
