April 21, 2014 – HD Electric’s Cap Check capacitor testers from HD Electric are designed to identify internal problems with a capacitor or capacitor bank, which according to the company, has proven to be a valuable asset in maintaining both pole-mounted and substation capacitors.

The testers identify bad or failing capacitors that may rupture upon energizing. Cap Check I and II are designed for pole mounted and individual capacitors and can enable a two-man crew to check a bank of 12 capacitors in about 20 minutes, it says. Cap Check III (shown here) is specifically designed for checking capacitor units in substation banks.
