  1. TYPE 23 POWER & DISTRIBUTION PO COLES

  2. NOTE The full presentation covers high voltage systems, switchboards, 600, 440, 115 volt systems, services and Essential Services, the P&D system. This was used to develop and teach technicians And the electrical damage control teams who would also have to attend my electrical workshops For CPD. All system content has been removed.

  3. Aims • To develop our understanding of the Type 23 Electrical Power System and develop the P&D model: • Covering: • The basic components of Generators. • How 450/600v Switchboards and ACBs operate. • 440v services through EDC’s and MCCB’s. • Distribution via Fuse Panels and Transformers. • Freestanding ROCOS.
