Hydro power is the world's largest source of renewable energy. Despite the recent media interest in solar & wind power, hydro has been a reliable and inexpensive source for more than 100 years. In the United States, hydroelectric facilities generate about 7% of the total power output. Read more...

A ground detection voltmeter is used to monitor a floating battery bank for inadvertent grounding of either side. Historically, a center zero analog meter has been used for this application. Read more...

A Weschler Digital Bargraph meter can be used to indicate Load Tap Changer position on a utility power transformer. The LTC adjusts the transformer voltage in discrete steps, to compensate for line or load changes. Nominal position is at the center of the step range. Read more...
