An adjustable throat for protecting electrical connections between two mating pieces of electrical equipment such as a transformer and associated switchgear is disclosed. The adjustable throat includes two telescoping tubular members each having flanges at one end thereof with oversized holes for connection respectively to a transformer and associated switchgear. The holes allow for vertical and horizontal adjustment to provide for final adjustment in these directions. One of the tubular members also has elongated open ended slots to allow the throat to be adjusted in and out to allow final connection to the switchgear without the need for minor movement of the gear.

Adjustable HV/LV protective throat

A safety enclosure system for a transformer is disclosed including a high voltage enclosure used in conjunction with a flip top hood on pad mounted transformers to provide an additional access restriction to the high voltage compartment after the hood has been opened. The high voltage enclosure is designed such that it is secured to the barrier plate separating the high voltage terminals from the low voltage terminals and after opening the enclosure is swung to the side, out of the way, for any operations in the high voltage compartment. The enclosure must then be closed before the hood can be closed and locked. This provides increased security for any further access to the high voltage compartment.
