Surge Arrester
Medium- and high-voltage surge arresters are the primary protection against atmospheric and switching over-voltages.
Products
include surge arresters used in medium- and high-voltage AC and DC
power systems, gaps not inherently self-clearing, capacitors of the type
generally used for protection against lightning, and resistors designed
to protect from lightning or other abnormal voltages to circuits or
equipment associated therewith.
Participation
in the development of technical documents and engagement with other
national and international organizations ensure NEMA Members' alignment
with industry-backed efforts that impact the surge arresters market and
create market demand through continued education and training of
customers.
