Client

London Stansted Airport is an international airport located in Essex. It serves 200 destinations across Europe, Middle East and Africa and serves as a base for a number of major European low-cost carriers.

Challenge

Stansted Airport serves over 28 million passengers each year. The airport is supported by an electrical distribution system that comprises 56 high voltage (HV) substations and 104 transformers as well as the associated high voltage and low voltage (LV) cables connecting from the main 33kV intakes down to street lighting supplies. It has different categories of supply importance from critical (affecting aerodrome licensing requirements) to non-essential. Supporting these different supply categories requires varying equipment and system design with a variety of switchgear types from different manufacturers.

Outcome
