class is 5 or *0
Accuracy limit factor (ALF) of protective
class is 5, *0, *5, *0, *0 or *0
Accuracy classes and their combinations:
Steady accuracy classes are 0.2S, 0.2, 0.5S, 0.5, 5P, *0P, PR and
PX; transient accuracy classes are TPS, TPX, TPY and TPZ. There are
1~6 pcs secondary winding(s) in a CT.

Non-effectively earthed neutral system
Main
Features:
The current transformer is SF6 gas
insulation, inverted frame, with the top of T type aluminum case
which there are secondary winding(s) and primary winding(s) inside.
The bushing is composite materials with silicon rubber umbrellas or
high strength porcelain. The secondary terminal leads which through
the metal tube are connected with the secondary terminals box which
at the base. There is a pressure relief device at the top of the
case, when the pressure is more than 0.8MPa if the current
transformer is discharge inside, the relief device will be broken
to release the pressure and send alarm information. There is a SF6
density monitor fix at the base, it can indicate the SF6 pressure
which inside the current transformer (its indicated value is the
SF6 pressure at *0ƒ), and it will provide
an information when the SF6 pressure is drop down to the minimum
service pressure of the current transformer, to remind the user
replenish the SF6 gas to the rated pressure.
