For Use With
The primary wire passing through the core, or by wrapping the secondary wires leading to the meter
A donut transformer is commonly used when AC current lev-
els to be monitored exceed 75 amperes. Current trans-
former rated 100:5 will provide a secondary current of 5 AC
amperes when a single primary turn is passed through the
donut with a 100 ampere load. The donut transformer pro-
vides additional isolation from the conductor. The secondary
leads are 2 feet long and may be extended up to 10 feet
using at least 12 gauge copper wire. If the distance is
greater than ten feet, please consult the factory.
A 50:5 amp donut is the lowest rating that Simpson normal-
ly carries. A donut can be used for ratings below 50 amps
by wrapping either the primary wire passing through the
core, or by wrapping the secondary wires leading to the
meter. This is shown on the next page. Other ratings are
available on special order. Call the factory with your specifi-
cations.
