Abstract
A partial discharge analysis (PDA) coupling device contains a shell, a potting material in the shell encapsulating at least two capacitors and a conductive, flexible joint connecting the capacitors. The joint may be a hose clamp or a spring which expands during the thermal expansion of the potting material while providing an electrical connection between the capacitors.
