RevenueSense™ Current Transformers offer electrical utilities both extended range and high accuracy to reduce electrical losses and increase revenue metering accuracy.
RevenueSense wide range, high accuracy CTs are designed for commercial and industrial applications. RevenueSense substantially reduces inventory, complexity and improves standardization for meter shop operations, particularly when used with GE Vernova’s kV2c FITZALL™ transformer rated meters

RevenueSense wide range, high accuracy CTs are designed for commercial and industrial applications. RevenueSense substantially reduces inventory, complexity and improves standardization for meter shop operations, particularly when used with GE Vernova’s kV2c FITZALL™ transformer rated meters
Encompass and RevenueSense CTs provide flexibility for commercial and industrial applications, indoor or outdoor service and bar-type or window-type configurations.
Per IEEE C57.13.6, a 0.15S class CT must maintain 0.15 accuracy from 5% of rated current through rating factor. This is a significantly tighter tolerance for error as compared to a standard CT: 2X better within rating factor and 4X better at light loads.
With GE Vernova’s RevenueSense CT’s, this tight tolerance of 0.15 accuracy is maintained for an extended range of 1% of rated current through rating factor. Similar to Encompass CT’s, moving from a standard CT to a wide range CT allows for a reduction in inventory, part numbers, and billing multipliers.
However, where Encompass CT’s offer equal performance over an extended range, RevenueSense CT’s offer improved high accuracy performance, allowing for increased billing accuracy and increased revenue.
The RevenueSense CT with rated range from 1% up through a rating factor of 3 covers the operating range of up to 8 other standard ratios, allowing for up to 90% reduction in inventory requirements. Additionally, the tolerance for CT error is tighter over the entire range, allowing for improved metering accuracy, particularly at light loads.
In this business case example, a commercial customer requires premium accuracy to maximize billing revenue. The assumed hours of operation for this business are Monday to Friday, 9am to 5pm. The business is closed weeknights and weekends.
The RevenueSense CT, with its premium accuracy increases billing revenue by $40.93 annually versus the standard CT. The additional cost of three high accuracy CT’s is roughly $60 in this example, yielding a payback in less than 18 months.

Instrument transformers perform a critical role in the management of power delivery systems by providing the voltage and current inputs to measure, protect and control power equipment. Therefore, accurate and reliable performance with a long-service life is vital so that revenue measurements can be made accurately and equipment can be reliably protected against surge or other system events.

SUPERBUTE dry-type instrument transformers are engineered and rigorously tested to provide a measurable difference in reliability and durability. Since the very first unit produced in 1955, SUPERBUTE instrument transformers have provided utilities with a number of benefits for enhanced safety and a lower total cost of ownership. SUPERBUTE is designed to meet IEEE C57.13 standards and ANSI standard mounting provisions, terminals, and construction.

SUPERBUTE is designed to meet IEEE C57.13 standards and ANSI standard mounting provisions, terminals, and construction.
Distribution class SUPERBUTE offers compact designs for more efficient application to solid-state metering and other modern installations.
Station class SUPERBUTE offers higher burden, higher thermal rating, and extra creep distance for substations or installations where higher ratings are required.
Field studies and accelerated life testing has shown an average operating life of more than 40 years, with reliability measures 3 times better than published industry benchmarks
Internal insulation is made from epoxy resin which is encapsulated in tough, elastic butyl rubber, dampening and minimizing the impact of high energy events
Unique dry-type construction ends oil leakage problems, eliminates breakage and vandalism issues, and does not support combustion
The dry-type design eliminates the need for oil testing or filtering and allows for a compact design which facilitates mounting flexibility for more economical installations such as on existing steel structures, inside a cabinet, or on a pole
Extensive vertical integration within the factory allows for standard lead times of 4-6 weeks, nearly half the industry average
GE Vernova’s proprietary formula of non-arc tracking butyl rubber showed no carbonization after 4,000 hours in salt-fog testing, compared to standard butyl rubber which failed after 107 hours or standard porcelain which failed after 400 hours under the sa
The outer shell of SUPERBUTE transformers are made with GE Vernova’s proprietary formula of butyl rubber, which is called HY-BUTE 60. This material adds the following timeless advantages over epoxy resins or porcelains designs:
Cross section of a JVS350 station-class voltage transformer showing Epoxy encapsulated with HY-BUTE 60 butyl rubber shell
Epoxy takes the place of oil as the internal insulation and winding impregnation. The advantage of this design includes:
SUPERBUTE instrument transformers are designed for quality and reliability with features engineered to withstand high voltage stresses and extreme environmental conditions, while delivering the highest accuracies possible, all within a compact design. The result is a reliable, long-lasting, easy to handle design that ultimately lowers total cost of ownership.
Lattice-type winding in a JVS350 station-class VT
Multi-gap type primary in a JKW350 station-class CT
Originally patented by GE Vernova, lattice-type windings have precise controlled positioning and distribution of each turn to reduce maximum voltage stress within the winding. This unique design also minimizes the possibility of partial discharges within the winding. The coil configuration, and the outer electrostatic shields distribute steep voltage fronts across the coil to reduce concentration of stress.
A unique multi-gap type primary by-pass on current transformers 600 amps and below protects windings during line disturbances or steep current wave fronts. The gaps are factory adjusted to fire at 5000-7500 crest volts, thereby by-passing surge currents up to 100 times rated, which could otherwise result in excessive voltages across the primary winding.
The use of high accuracy instrument transformers with solid-state metering allows for improved billing accuracy and/or the potential to reduce inventory requirements. GE Vernova offers high accuracy and extended range ratings which meet the accuracy needed for these applications. Since introducing the first dry-type high-accuracy transformer solution in 1991, GE Vernova’s high accuracy product line has grown to a portfolio that includes a wide variety of voltage classes up to and including 69 kV.
SUPERBUTE transformers require up to 30% less height and up to 40% less floor space compared to the leading oil-filled designs, and can be mounted in any position. This allows substation design flexibility including mounting on a substation steel structure or a pole.
Even with 30% less height, standard units can be used in environmentally severe conditions and in high altitude (10,000ft) applications. Station class units have creep distances that exceed the requirements for even the next-level voltage class.
