Manitoba Hydro Bipoles I and II Smoothing Reactor Replacement

Manitoba Hydro Bipoles I and II Smoothing Reactor Replacement

Manitoba Hydro determined that the existing Bipole I and II oil-filled smoothing reactors needed to be replaced. The project involved removal of the existing Bipole I and II oil-filled smoothing reactors at Dorsey, Radisson, and Henday converter stations, and replacing them with dry-type, air-cooled reactor coils. The project also included addition of new DC current measuring devices (DCCTs) for each pole at each converter station.

Teshmont’s scope of work included preparation of construction specifications including Equipment Installation Packages (EIPs), drawings, schedules, etc. for the Dorsey, Radisson and Henday converter stations covering:

  • Removal of the existing Bipole I and II oil-filled smoothing reactors (8 electrical EIPs);
  • Installation of the new Bipole I and II air-cored, air-cooled smoothing reactors on existing or new foundations (8 EIPs); and,
  • Relocating the existing voltage divider, lightning arrester and/or any other associated equipment with the installation of the dc smoothing reactors on new foundations and support structures, as required (8 EIPs).
  • Witness smoothing reactor factory tests

Teshmont performed the technical evaluation of the construction tenders, and ultimately prepared award recommendations for Manitoba Hydro.

Teshmont prepared stand-alone and system commissioning procedures for the new smoothing reactors (8 commissioning procedures).

Teshmont also developed technical specifications, performed the tender evaluation and prepared award recommendations for the associated equipment including DCCTs, voltage dividers, grounding switches, etc.

Teshmont prepared marked-up “as-built” drawings, and revised / cancelled Manitoba Hydro drawings and manuals affected by the project.
