  • Power Quality

    The quality of power coming into a residence or commercial operation has always been important. You expect a consistent and constant flow of electricity to power whatever you're doing.

    Years ago, homes and businesses could tolerate a certain amount of inconsistency. Other than outright power outages, life and commerce could hum along and never notice any differences in power quality, up to a certain point that is.

  • Why is Power Quality Important?

    Before we begin to discuss why power quality is important, let's answer a few questions about what it is, what it involves and what affects it.

    From the utility or provider standpoint, the main concern is a consistent and uninterrupted voltage supply. Remember that this is not a constant value, but a voltage range. While we might talk about, for instance, a 120-volt AC supply, in reality that is a nominal value for a range.

  • Energy Savings Add Up Quickly with LED Parking and Area Lighting

    Maybe like you, I’ve recently begun switching out my compact fluorescent (CFL) bulbs with LED replacements in my table and ceiling fixtures. The energy savings aren’t huge, maybe 5 watts per lamp, and certainly not what I initially managed when switching from old 60 watt incandescents to the 13 watt CFLs. But every little bit helps, plus, the LEDs could last 15 or 20 years, depending on use, so I won’t have to worry about replacing them again for another decade or two.
