Model JAB-0CV 600V

Indoor Current Transformer 10 kV BIL, 200-3,000 A
Window Size 4.50” X 3.50”

Application

Designed for indoor service; especially designed for installation over the secondary
bushings of pad mounted transformers from 75 kVA to 3,000 kVA.
This special version of the JAB-0CV current transformer is designed for use on heavily
loaded pad mount transformers operating in high temperature environments up to 85 °C.
For mounting and application information, including use at higher voltages, and matching
the current rating to the pad transformer thermal capability, please refer to the
Applications Information section of catalog GEP-9186.

Model JAB-0CV

Construction and Insulation

The core and coil assembly is encapsulated and cast in
polyurethane resin. The material has excellent electrical and
mechanical properties over a wide temperature range, and is UV
resistant. The intended application for this CT is in a secure
location where terminal covers and sealing provisions are not
required, preferably the locked secondary compartment of a pad­mount transformer.

Core and Coils

The core is made from high quality grain oriented silicon steel,
annealed under rigidly controlled factory conditions.
The secondary winding is made of heavy enameled copper wire.
The secondary windings are evenly distributed around the core
for maximum accuracy and resistance to stray fields from
adjacent conductors.

Terminals

Secondary terminals are tin plated brass, compression type with
a 0.275” diameter cross-hole for wiring and a 1/4-28 clamp
screw.

Polarity

H1 and X1 are identified by white dots. Secondary terminals are
labled X5, X4, X3, X2, X1.

Primary Conductor

These transformers are primarily intended for installation over
the bushing and terminal blade of pad mount transformers,
which then forms the primary conductor.

Nameplates

The nameplate is laser engraved aluminum. It is attached to the
side of the unit and has provision for attaching the user’s
identifying tag. The nominal current rating is on both faces of the
unit in large numerals.

Mounting

The transformer can be mounted in any position but is usually
installed on the pad mount tranformer terminal blade using the
“grabbers”. The transformer also has two mounting holes
allowing it to be attached to a mounting bracket.

Maintenance

These transformers require no maintenance, other than
occasional cleaning, if installed where air contamination
is severe.
