How can I prevent external through-faults from causing damage to transformers?
The SEL-2414 offers a Through-Fault Event Monitor that gathers data such as current levels, duration, date/time for each fault and calculates an energy (I^2t) value. Utilize this function to schedule maintenance based on the accumulated through-fault current over time (Page 6).
