Being a member of a company that supplies SCADA systems, mainly for electric
utilities, and since we are evaluating developing a new RTU or integrating
a RTU from a different supplier, I?d be interested on receiving information
about suppliers of RTUs and the specifications of their RTUs (pole mount and
substation) .

There are several suppliers of RTUs in the Remote Terminal Units (RTU)
category of the Products directory of the ElectricNet OnLine Directory

The best RTU supplier by far is GE-Harris (formally Westronics) in Calgary
Canada. We have used their RTUs in all of our projects and I am continually
amazed how versatile their D20 family of RTUs is.
Their pole mounted RTU known as the DART, is one of the only poletop RTUs I
know that supports transducerless measurements, that is connect directly to
the CTs and PTs (Voltage Transformer). The DART uses DSP technology to
calculate additional parameters such as phase, power factor, power, energy,
etc. The DART can also be used to do fault detection and isolation.
GE-Harris have a range of distributed I/O modules which connect to a high
speed link in the substation which reduces the cost of installation by
reducing labor and wiring. One of the I/O modules, the D20AC module permits
transducerless measurements in the substation. Think of the cost savings if
you could eliminate most transducers in a substation. Their latest product
the D25 is probably their most amazing product yet. I won't attempt to
describe this product as it does so many things.
GE-Harris has a large protocol library which allows the D20/D200 RTU to
talk to most IED (Intelligent Electronic Devices) such as protection
relays, revenue meters, PLCs, other RTUs, etc. What I like most about the
D20 family is its ability to scale from a small RTU to a very large RTU
without having to throw anything away. When you decide to implement
Substation Automation, you use the same hardware and simply add
applications and protocols. GE-Harris has a large range of Substation
Automation applications and I believe they are the number one suppliers of
RTUs and Substation Automation solutions in the world. Companies such as
Siemens, ABB, and others have supplied D20 RTUs in many of their projects.
Anyone interested should contact GE-Harris directly. The GE-Harris person
to contact is Gary Moore at garym@hdap.com or phone Canada (403) 243-3335
