System Protection
The System Protection group consists of more than 30 highly qualified
engineers. This group can be augmented with additional staff from our
Controls, Automation, and System Studies teams.
System Protection Experience
TRC has extensive experience providing relay settings, studies and
calculations for numerical, static and electromechanical relays, NERC
compliance support, outage and fault analysis, IEC 61850 applications, as
well as a wide variety of substation automation applications. TRC has performed fault coordination studies and provided calculation documents to meet
our client’s standard format or provided our own if there is not a standard
practice. TRC’s relay setting and studies work has involved power
transmission, generation and distribution equipment from Extra-High Voltage
(EHV) to distribution circuits. TRC has specified, set, tested and commissioned relays on virtually every type of power system equipment, including
transmission lines, power transformers, capacitors, substation busses and
generators. TRC has provided settings for many of the available numerical
utility relay manufacturers, including Schweitzer Engineering Labs (SEL),
General Electric (GE)/Multilin, Areva, Asea Brown Boveri (ABB), Basler
Electric, Cooper Power Systems, Siemens, and many others. TRC has also
provided settings for many of the electromechanical relay (EM) types still in
use. TRC has designed, installed, set/programmed and commissioned
substation Automation/Integration, IEC 61850 platform (Smart Grid) systems
using Cybectec, SEL, Orion, Telvent, GE, Allen Bradley, and many others.
TRC will either meet our client’s standard or recommend and install a
successful design if there is no standard.
