GE

is a revenue metering current transformer which

Energy Connections

Model JAB-0S RevenueSenseTM

Revenue Metering Current Transformer

Application

RevenueSenseTM

maintains IEEE 0.15 accuracy class from 1% of rated current up
through rating factor. This is accomplished using the specialized
amorphous core material which minimizes electrical core losses.
The result is an extremely accurate CT that can maintain high
accuracy over a extended range of current. Model JAB-0S is
designed for indoor service; specifically designed for installation
over the secondary bushings of pad-mounted transformers.

Construction and Insulation

The core and coil assembly is encapsulated in resin within a
molded case. The case is molded with GE Valox thermoplastic
polyester resin. This tough material has excellent electrical and
mechanical properties over a wide temperature range, has low
water absorption and is resistant to oil and a variety of
chemicals. A polyurethane resin filling completely encapsulates
the winding, leads and terminals to form a waterproof unit.

Core and Coils

The core is manufactured with high-efficiency material that
reduces energy losses, allowing from higher accuracy over a
wider range. 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. A shorting device is provided and interlocked to the
terminal cover. The terminal cover is made of a clear plastic.
Provision is made for sealing the cover.

Polarity

Primary and secondary marks H1, H2 and X1, X2 are molded into
the case. In addition, H1 and X1 are identified by white dots.

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
top 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 transformer terminal blade using the
Valox “grabbers”. The grabbers are removable and 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,
