PROJECT TITLE :

Ensuring Switchgear Integrity in High-Power Installations

ABSTRACT:

Offshore installations usually push switchgear to the limit of their rated current and short-circuit withstanding capacity and, in some cases, even above. This can be because of the increase in the amount of electrically driven loads and also the severe area and weight restrictions offshore. The same is being seen now for onshore installations where there is typically restricted area for brand spanking new production facilities. Expansion of existing plants results in both increased rated and short-circuit currents and, in some cases, a lot of complicated switching arrangements, a number of which may cause switchgear ratings to be exceeded. There are several techniques that can be used to address such situations. In some cases, it is sufficient to produce interlocking to stop unacceptable operating conditions from occurring. In different cases, it's necessary to add pyrotechnic fault current limiters (FCLs) to stop equipment destruction ought to a brief circuit occur. Like all equipment, it's necessary to perceive how FCLs operate in order to make certain that they're correctly integrated into the Power System. This paper can review several techniques that have been used in applications to ensure switchgear integrity. There's a special specialise in the right integration of FCLs. We tend to think about such measures to be an integral half of the switchgear, so allowing verification of all safety features throughout the equipment design and testing phases prior to arrival at website. The project specifications should include all planned future growth to ensure that the facility system and switchgear be designed accordingly.
