Using Pyrotechnic Current-Limiting Devices: A Case Study of What Went Right

The trend toward electrical rather than mechanical drivers for offshore installation has led to the implementation of large electrical systems and power generation. Due to the offshore environment constraints, such as weight and footprint limitations, most of the installation remains operated at voltages of 13.8 kV and lower, which leads to specific constraints on the electrical network design. This article provides an overview of the implementation of pyrotechnic current-limiting devices from the design stage through precommissioning, commissioning, and operation.
