National Grid calls upon Sulzer for bespoke motor redesigns

02 June 2023

In the face of mounting pressure on global energy markets, utility companies are striving to guarantee consistent power supply for millions of people. When National Grid encountered maintenance challenges with two motors at crucial gas booster station sites, it turned to Sulzer for assistance.

Gas booster stations are critical strategic components in the UK’s gas supply network. At these facilities, motor-driven compressors are used to ensure that gas is distributed to where it is needed. Consequently, any reliability issues at these sites can adversely affect gas supplies if not resolved promptly.

When motors throw a temperature tantrum
Initially, National Grid identified an issue with two large 16MW motors, one installed at a compressor site near Wormington in Gloucestershire and the other located close to Churchover, near Rugby. 

The problem arose when resistance temperature detectors (RTDs) embedded inside the motor windings began to fail, compromising the ability of operators to gain accurate temperature readings and condition monitoring data. As the motors were Ex rated, this also threatened the compliance of the installations.
