Capacitor Testers Identify Internal Problems

HD Electric Co.'s Cap Check line of capacitor testers are designed to identify internal problems with a capacitor or capacitor bank and have 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. Cap Check III is specifically designed for checking capacitor units in substation banks.
