Hydran M2
The Hydran M2 is a compact permanently mounted on-line transformer monitoring device that will alert personnel to developing fault conditions. It continuously monitors a composite value of various fault gases (in ppm) or a Hydrogen gas only value (depending on sensor purchased). In addition it tracks moisture in oil (reading in %RH and ppm).
With additional sensors added, the Hydran M2 can also compute transformer mathematical models based on IEEE® and IEC® standards to provide further information on the performance of the transformer.

Application
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
Application Overview: Secondary Metering with Current Transformers
Encompass and RevenueSense CTs provide flexibility for commercial and industrial applications, indoor or outdoor service and bar-type or window-type configurations.
Redefining Special High Accuracy
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.
Standard CT Test Limits
RevenueSense Test Limits
Results and Benefits
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.
Business Case Example
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.
Assumptions:
- Nominal system with current of 200A
- System impedance of 0.1Ω
- Line to ground voltage of 277V vfactor of 0.9
- per kWh of $0.09
Load Conditions:
- Load is 100% of nominal current (200A) for 8 hours each weekday
- 10% of nominal current (20A) for 16 hours each weekday
- 5% of nominal current (2A) during weekends
Results and Benefit
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.
