Improve Reliability and Control Distribution
System Dynamics with OptiSensors™
The difference between conventional distribution
monitoring devices and OptiSensors™ is like
comparing signaling devices to MRIs.
With OptiSensors™, engineers get an extremely
detailed, real-time view of distribution system dynamics
as they occur – not in retrospect after a truck has
rolled.
For instance, for Demand Response and Volt/VAR Control
initiatives to be successful, a high average accuracy is
needed.
For Conservation Voltage Optimization, measurements
such as power factor correction, accurate voltages
across the feeder, high dynamic current range, and fast
operational responses are required.
To improve Power Quality, high frequency response and
high sampling rates are critical to identify transients
and harmonics. To accurately determine fault locations,
utilities need precise measurement of feeder fault
impedance before rolling restoration trucks.
Medium voltage OptiSensors™ give you
this critical intelligence.
- OptiSensors™ measure voltage,
current and power factor on all 3 phases of
distribution feeders through patented, optical crystal
technology that take and store 15,000 measurements per
second.
- OptiSensors™ are highly accurate
(± 0.5%) – versus competitive sensors with accuracy of
± 5%.
- OptiSensors™ are low-cost,
lightweight (8-10 lbs), and can typically be
installed in less than 3 man-hours.
- OptiSensors™ require no service
interruption to install.
VOLTAGE CLASS OPTIONS
Distribution planners are challenged by new conditions
affecting performance (capacity constraints, changing
load profiles, distributed generation, renewables,
etc.). To address these challenges, OptiSense provides
two versions of the OptiSensors in a variety of voltage
classes.
- The OptiSense voltage-only sensor accurately
measures line to ground voltage.
- The OptiSense combo sensor accurately measures both
line current (including direction of flow) and line to
ground voltage.
Both sensor types are available in the 15kV, 25kV and
35kV classes. The 46kV class sensors are currently in
development and will be available soon.
