A method is provided for determining a shorted thyristor cell in a bridge that supplies a load from a source, the bridge including a plurality of the thyristor cells. The method includes the step of sequentially gating each of the cells to a conducting state, so that only one cell is gated at one time; providing at least one current transformer in the bridge; generating a current flow that passes through the bridge including the one cell that is gated; observing current in the at least one current transformer to determine a short in one of the cells the that is not gated; and determining a shorted cell based on the step of observing current in the at least one current transformer.

Method for detecting and identifying shorted thyristors

An apparatus and method for mounting electrical devices in a housing at an angle relative to the ground is provided. The apparatus comprises a housing having a top, bottom, and sides, each of which may be open, closed or ventilated. One or more electrical devices are located in the housing and are oriented at an angle relative to the horizontal ground. The electrical devices may be silicon controlled rectifiers that serve as a power bridge between an exciter and a power generator. A method for mounting electrical devices in a housing at an angle relative to the horizontal ground is also provided.
