INTRODUCTION
This instruction manual details information about installing, operating, and maintaining ventilated dry type transformers. Each transformer has
its own specification and unique construction features. These features are detailed in the transformer outline and nameplate drawings.
This instruction bulletin is not an application guide for the ventilated dry type transformers or a substitute for adequate training in safe working
procedures for this and related electrical equipment. Installation of this electrical equipment may require special licenses or training. Consult
applicable national, industry, and local codes for specific requirements. The successful operation of any transformer depends on various
factors such as installation, loading, service conditions, and maintenance. Electrical systems in which transformers, along with vacuum or SF6
circuit breakers, are used are capable of high frequency over voltages which will not be suppressed by lightning arresters. These medium
voltage systems may require a detailed, high frequency over voltage system analysis and/or the addition of high frequency over voltage
protection. The transformer should be installed in conditions as specified in ANSI/IEEE Section C57.12.01 Usual Service Conditions, unless the
transformer is designed specifically for operation in conditions other than the usual service conditions.
NOTE: If additional information is needed that this instruction manual does not cover, visit us on the web a www.maddoxtransformer.com or
call the Company Sales Office.
