Model JAD-0S RevenueSenseTM
Revenue Metering Current Transformer
Application
RevenueSenseTM is a revenue metering current transformer which
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 JAD-0S is
designed for indoor service, and is available in bar-type or windowtype designs.
Features
Voltage Class: 0.6 kV
Frequency: 50-60 Hz
Window Size: 5.75”
Insulation Level: 10 kV BIL
Application: Indoor/Outdoor
Benefits
Maximize revenue metering accuracy with special high accuracy
rating extended beyond IEEE requirements
Simplify CT selection and billing multipliers, improving
productivity and minimizing risk of error
and operational costs

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.
The 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 for higher accuracy over a wider
range. The secondary winding is made of heavy enameled copper
wire evenly distributed around the core for maximum accuracy
and resistance to stray fields from adjacent conductors.
Terminals
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 polarity marks H1 and X1 are molded into
the case.
Nameplates
The nameplate is laser engraved aluminum and is attached to the
of the unit in large numerals.
Primary Conductor
Removable primary bars are formed from 1/4”x 4”tin-plated, flat
copper bar, with 1/4”spacing between bars on multiple bar
assemblies. The bars are retained by insulated and ventilated end
caps, which permit the bars to be rotated to any desired
primary arrangement. A potential connector is provided adjacent
to one end cap. Primary bars are available in 11 7/8”and 14
1/4”lengths, each provided with four bolt holes at each end.
Baseplate and Mounting
plate is available, made of stainless steel. It is attached to the
transformer with two bolts.
Maintenance
These transformers require no maintenance, other than
occasional cleaning, if installed where air contamination is severe.
