Instrument transformers
ZCT, EVT and special purpose CT
ꢀ Description
CP-619
FUJI can supply special purpose CTs,
ZCTs (Zero-phase current
transformers) and EVTs (Earthing
Toroidal type ZCT
ZCE2A
voltage transformers) as well as
standard FUJI instrument transformers.
Some of the versions are described
below.
CED and ZCED
CP-620
The CED and ZCED are split-
construction types.They can be
mounted in position without
disconnecting the cables.
CED: Epoxy-molded split-toroidal type CT
ZCED: Epoxy-molded split-toroidal type
