Second Wind Introduces 8 Input/Output Option For Phaser® Power
Transducer
 28
October 2001—Second Wind Inc., an innovative provider of supervisory
monitoring and control solutions to the energy distribution market,
has announced here today at the IEEE/PES Transmission and Distribution
Exposition, the availability of its 8 Input/Output (I/O) enhanced
Phaser® product. The Phaser 8 I/O provides utility supervisory
control and data acquisition (SCADA) systems with the ability to
control or monitor any combination of 8 independent and separately
configurable outputs or inputs in addition to monitoring all parameters
of a feeder or transmission line. By acting as a distributed mini-remote
terminal unit (RTU), the enhanced field configurable 8 I/O Phaser
provides substation engineers with the most cost effective solution
to expanding their SCADA system. The ability to connect hundreds
of networked Phasers to a single SCADA port provides the capability
to add thousands of additional discrete monitoring points to existing
SCADA systems.
With an 8 I/O Phaser acting as a mini RTU, the user can add RTU functionality
in small increments to meet customers’ needs, with the capability
for expansion as they add more equipment to a substation. The Phaser’s
compact size allows engineers the ability for convenient mounting
in existing equipment in the substation yard by using either its
fiber loop or an RS485 communications wire, thus eliminating the
need to run voltage, current and control wires from the control house
to the equipment in the yard. By having multiple Phasers on a local
loop, the functionality of a large RTU can be achieved while maintaining
the advantage of a distributed system.
Mr. Walter Sass, Second Wind President, said, “This powerful
new option to our expanding Phaser product line provides the user
with a flexible, very cost effective, convenient solution to remotely
read inputs or set/reset outputs of the SCADA system using either
RS485 or fiber networks. It provides all of this at a fraction of
the cost of comparable functional systems, while still maintaining
all of the Phaser functionality...three phase measurement of voltage
and current, with the standard 60 measured and calculated variables.
By having multiple phases on a local loop, the functionality of a
big RTU can be achieved, while maintaining the advantage of a distributed
system.”
The small size and local control functions make the Phaser ideal
for other distributed applications, such as pole–top applications.
A typical pole–top application would use the Phaser 8 I/O connected
to a radio communication system. It would monitor the power flow
on the transmission/feeder line, and provide supervisory control
to other pole–top mounted devices such as reclosing circuit
breakers and/or capacitor banks. The SCADA master would receive power
and status input data from the Phaser, and issue commands to the
Phaser to control the local devices.
