Abstract

The fault current limiting transformer (FCLT) presented by J. Brochu et al. (see IEEE Trans. Power Delivery, vol.13, p.233-40, 1998) was designed with the purpose of increasing the total capacity of a transformer station without increasing short-circuit currents. In situations where such an IPC is closely coupled with parallel transformers, the FCLT installation can be simplified. The purpose of this letter is to describe the enhanced capabilities and outline the basic design criteria for this innovative IPC application. An application example provides typical component ratings, space requirements, and a budget cost estimate
