This standard does not cover the electrical and mechanical requirements of any accessory devices that may be supplied with the transformer. These transformers are rated 5 MVA and smaller, with the high-voltage limit of 34.5 kV system nominal voltage and below, and with low-voltage limit of 15 kV system nominal voltage and below. <> If a transformer pad or substation is not contained, leaking mineral oil can penetrate the ground, causing an environmental hazard. Certain electrical, dimensional, and mechanical characteristics are set forth as well as certain safety features of three-phase, 60 Hz., mineral-oil-immersed, self-cooled, pad-mounted, compartmental-type distribution transformers. High and low voltage underground cables from below enter the terminal compartments directly. Divide the 110 percent volume required by the capacity per square foot of stone. <>stream Add the square foot of containment required (Step 3) to the square foot of the pads (Step 4) to find the total square foot area. Certain electrical, dimensional, and mechanical characteristics are set forth as well as certain safety features of three-phase, 60 Hz, mineral-oil-immersed, self-cooled, pad-mounted, compartmental-type distribution transformers. Pad-mount transformers are available in various electrical and mechanical configurations. These transformers are rated 10 MVA and smaller, with the high-voltage limit of 34.5 kV system nominal voltage and below, and with low-voltage limit of 15 kV system nominal voltage and below. xmp.did:07801174072068118DBBAB668637C198 Also available is the Geomembrane Liner System with Barrier Boom.

Three-phase pad-mounted compartmental type transformer. These transformers are generally used for step-down purposes from an underground primary cable supply. transformer Our products and services cover the complete standards development lifecycle...and beyond. figure 20a H��Wˎ$� ��W�T�(�z����/���s�6`��f�̬��E�a�}0�Q�I���/����˯N��-������_��?��7��(��]����n&�=�n�x�9N��mWi���]�*���n���2��سd�pW?i�K�[����#��q@,��w?��Y�o��F���D�Qk�a۫�{���ʮ��G�A��č��0��!�{�ߎY���;��-�9��j����K� JUX�7��p���g�ޭ��a��랰֯�noދ����S�ܞ�'�X��I�΅ֹ�W��Q��}�J�ن���ۭ����.w�_�%�~ܓ��eOmL�/��]�k�S��?�/¾1^�4���S=m�sWy��~o��R��W�v|�'��n�xzX�,�+���SD.��RN����r$̉������k�%/ Single-phase transformers may be specified for hydraulic stations because of transport Add 10 percent freeboard to account for rain and snow. Whatever your requirements, our custom solution will be durable enough for the most stringent spill control requirements. application/pdf The top of the tank has a cover secured with carriage bolt-nut assemblies. The bayonet mount fuse protects against secondary faults and transformer overload and is a field replaceable device. 2018-07-03T03:05:05.000-04:00 A length of 24 feet would provide a total area of 312 square feet to meet our oil containment needs. H�*T�w6PH/V�w�5Pp�WT 0 7 This standard covers the connector, bushing, and terminal arrangements for radial or loop-feed systems. 163 0 obj Contact us for your secondary containment needs. It does not apply in a network area, or in URD / UCD areas. Pad-mount transformers operate on medium-voltage distribution systems, up to about 35 kV. proof:pdf 47 0 obj To comply with SPCC regulations, an electric utility wants to install secondary containment around its 600-gallon transformer. Add 10 percent to the volume of oil to accommodate precipitation or snow. Most of the spill containment products required assembly, inflation or both. from application/x-indesign to application/pdf default Either certain minimum dimensions or certain specific dimensions shall be specified. Determine the depth of the secondary containment area based on existing stone depth and the site layout. Pad-mounted transformers are made in power ratings from around 15 to around 5000 kVA and often include built-in fuses and switches. Pad-mount transformers have self protecting fuses consisting of a bayonet mount fuse placed in a high voltage compartment, with a back-up high energy current limiting fuse in series to protect against secondary faults and transformer overload. A padmount or pad-mounted transformer is a ground mounted electric power distribution transformer in a locked steel cabinet mounted on a concrete pad.
