0.*0MPa Rated operating pressure of the
SF6 gas is 0.*0MPa
Minimum operating pressure of the SF6 gas
is 0.*5MPa
Instrument security factor (FS) of
measuring 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.
Arcing distance

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
*0Æ’), 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.
