Transformer Switching & Protection Solution

As US energy consumption continues to grow, utilities are tasked with adding additional generation capacity to their system. With this additional capacity, however, comes higher system fault levels. Transformers, which can be vulnerable to damage when external and internal faults occur, serve as one of the most critical and costly pieces of substation equipment that utilities should look to protect. Failure to select a proper primary side protection device can have a devastating financial and customer interruption impact. The Southern States circuit switcher line of products address many of the shortcomings associated with other transformer protection devices, such as power fuses or circuit breakers. Circuit Switchers can account for secondary-side faults, larger loads, relay schemes that coordinate with upstream and downstream devices, as well as high transient recovery voltage (TRV) transformer through-faults.
