For replacing position detecting switches in a breaker, a mechanical breaker switch is moved to permit removal of first and second position detecting switches, the first indicating whether the mechanical breaker switch is in a first position by transitioning between first and second states when disposed at or greater than a first threshold angle, the second indicating whether the mechanical breaker switch is in the second position by transitioning between first and second states when disposed at or less than a second threshold angle. The position detecting switches are removed and replaced with replacement position detecting switches. The first replacement switch is adjusted to transition between the first and second states at when disposed at or greater than the first threshold angle, and the second replacement switch is adjusted to transition between the first and second states at when disposed at or less than the second threshold angle.

Disclosed is a method of reconditioning a vacuum interrupter that comprises determining whether the vacuum interrupter is suitable for reconditioning. Where the vacuum interrupter is suitable for reconditioning, the method comprises reducing pressure inside vacuum interrupter using magnetron pumping, and/or forming at least one hole in an endcap of a vacuum envelope of the vacuum interrupter, cleaning components of the vacuum interrupter inside the vacuum envelope by introducing at least one cleaning solution into the interior of the vacuum envelope through the at least one hole in the endcap, removing the cleaning solution from the interior of the vacuum envelope, installing a plug in the at least one hole, wherein the plug has getter material on a surface thereof facing the interior of the vacuum envelope, and vacuum sealing the plug to the at least one hole such that a vacuum is re-established in the interior of the vacuum envelope.

A flexible magnetic coil for determining ion migration rates inside a vacuum device can include a plurality of insulated copper wires held together as a bundle. A positive pole can be connected to a first end of the bundle for receiving a positive DC voltage. A negative pole can be connected to a second end of the bundle for completing a circuit with the positive pole. A DC voltage ranging from ten volts to four thousand volts from a power supply can be connected to the positive pole, the negative pole, or combinations thereof. The bundle can be a loop and can form a circuit when the DC voltage is applied to the loop. The bundle can create a flexible electromagnetic field of at least one Gauss around the vacuum device using a calculation of a number of turns of insulated copper wire multiplied by applied DC current.
