Abstract
A sensor to monitor health of surge arresters such as metal oxide arresters is disclosed. The sensor includes a housing; a sensor assembly contained in the housing, the sensor assembly including an electronics board to receive, transmit, process, and store signals; and a voltage measurement strap extending around a periphery of the housing, the voltage measurement strap being electrically connected to the electronics board and configured to measure voltage using electric field.

A surge arrestor sensor configured to monitor a health of a surge arrester, comprising:
- (a) a housing;
- (b) a sensor assembly contained in the housing, the sensor assembly including an electronics board to receive, transmit, process, and store signals;
- and
- (c) a voltage measurement strap extending around a periphery of the housing, the voltage measurement strap being electrically connected to the electronics board and configured to measure voltage using electric field.
A surge arrester sensor, comprising:
- (a) a housing having a sensor assembly contained therein, the housing including first and second spaced-apart ends interconnected by a sidewall;
- (b) a voltage measurement strap extending around a periphery of the housing and electrically connected to the sensor assembly;
- and
- (c) a central shaft extending through a center of the housing, the central shaft having a first distal end attached to an energized end of a surge arrester and a second distal end connected to an energized conductor.
