Installation
CSH120 & CSH200
Zero Sequence CT
DANGER
Assembly
DE51678
HAZARD OF ELECTRIC SHOCK,
EXPLOSION, OR ARC FLASH
b Only qualified electrical workers
should install this equipment. Such
work should be performed only after
reading this entire set of
instructions.
b NEVER work alone.
b Before performing visual
inspections, tests, or maintenance
on this equipment, disconnect all
sources of electric power. Assume
that all circuits are live until they
have been completely de-energized,
tested, and tagged. Pay particular
attention to the design of the power
system. Consider all sources of
power, including the possibility of
backfeeding.
b Always use a properly rated voltage
sensing device to confirm that all
power is off.
b Only CSH120, CSH200, and
CSH280 zero sequence CTs are
used for direct residual current
measurement. Other residual
current sensors require the use of an
intermediate device, CSH30,
ACE990 or CCA634.
b Install the zero sequence CTs on
insulated cables.
b Cables with a rated voltage of more
than
1000 V must also have a grounded
shielding.
Failure to follow these instructions will
result in death or serious injury.
1 Group the MV cable(s) in the middle of
the zero sequence CT.
2 Use non-conductive binding to hold the
cables.
3 Insert the three medium voltage cable
shielded grounding cables through the
zero sequence CT.

Assembly on MV cables. Assembly on mounting
plate.
CAUTION
Connection
HAZARD OF NON-OPERATION
Do not connect the secondary circuit of the CSH
zero sequence CTs to ground.
This connection is made in Sepam™.
Failure to follow this instruction can cause
Sepam™ to operate incorrectly.
Connection to Sepam™ Series 80
b To residual current Ir input, on connector , terminals 15 and 14 (shielding)
b To residual current I'r input, on connector , terminals 18 and 17 (shielding)
Recommended Cable
b Sheathed cable, shielded by tinned copper braid
b Minimum cable cross-section 0.93 mm² (AWG 18)
b Resistance per unit length < 100 mΩ/m (30.5 mΩ/ft)
b Minimum dielectric strength: 1000 V (700 Vrms)
b Connect the cable shielding in the shortest manner possible to Sepam™
b Flatten the connection cable against the metal frames of the cubicle.
The connection cable shielding is grounded in Sepam™. Do not ground the cable by
any other means.
The maximum resistance of the Sepam™ connection wiring must not exceed 4 Ω
(20 m maximum for 100 mΩ/m or 66 ft maximum for 30.5 mΩ/ft).
