Tap-changer and bushing selection program Compas

Selecting components can be a challenging task for transformer design engineers, especially during the tendering stage as time can be of the essence. Engineers need to balance cost optimization with product performance, while taking into consideration the large variation of tap-changer and bushing types.

Compas is a software application that helps engineers to select the correct tap-changer and bushing. Based on basic electrical characteristics well known to transformer engineers, the tool suggests the optimal component based on performance and cost. It also serves as a quick and easy tool for service engineers in retrieving product information when working on site.

Key features in the new and enhanced web based application:

  • New modern, streamlined and intuitive interface
  • Delivery times now available in Compas
  • Bushing portfolio now available in Compas
  • Ability to send product inquiry directly to Hitachi ABB Power Grids sales representative based on user selection
  • Improved document and drawing library

New feature from August 2019:

Tap-changer search now includes motor-drive mechanism.
