A fault in SH Netz's 110 kV network tripped several substations and set a surge arrester on fire at the Friedrichstadt substation; most customers were back within about two and a half hours. Overvoltage events drive downstream equipment claims, and the utility is now telling customers to check their own electrical installations for damage.
