WG 32

High-voltage switchgear and controlgear - Part 212: Compact Equipment Assembly

This Standard will specify the service conditions, rated characteristics, general structural requirements and test methods of the prefabricated assembly of the main electrical functional units of a HV/LV Distribution Substation for alternating current of rated operating voltages above 1 kV and up to and including 52 kV on the HV side, service frequency 50/60 Hz, to be cable-connected to the network.
CEADS is intended to become part of a Distribution Substation assembling the HV equipment, the power transformer and the LV equipment duly interconnected. However relevant provisions of this standard are also applicable to designs where not all of these functions exist.
This Compact Equipment Assembly for Distribution Substation (CEADS) as defined in this standard is designed and tested to be a single product with a single serial number and one set of documentation.
