- Electrical
Power System Protection and Control,
Coordination Analysis and Studies
- The reliability of your electric system
is highly dependant on its protection
system. A mis-calibrated or incorrectly
designed protection system will either
produce unwanted outages or will damage
your electrical system. We at IEG can
analyze your electrical system and
determine if it is properly protected,
determine the optimum settings for the
protective relays in accordance with your
load patterns, prepare and deliver
maintenance and operating instructions
and supervise any construction process
required for the system’s
optimization. We can also help you
modernize existing systems for using
state of the art solid state static
protection devices. These new devices can
provide remote annunciation of relay
operations and permit programmed or
remote calibration, thus providing a
reduction in operation and maintenance
costs. Some of our typical services are:
- Thorough review of
your actual Electrical System.
- Comprehensive
analysis of the original design.
- Comparison of
design objectives with actual use.
- Physical
inspection of the system.
- Review or prepare
maintenance and operations procedures.
- Recommend test
equipment.
- Deliverables: A
comprehensive report which contain
the audit results with recommendation
on how to optimize your system.
- Testing and
Maintenance of Substation Overall
Protection and Metering, Control and
Signaling Equipment - All tests
will be geared to the objectives which
they are intended to meet and will be
streamlined within the objectives. These
test objectives are: Acceptance Test (New
products first time applied and Test on
each product received), Installation
Tests, Maintenance or Functional Tests
and Repair Tests. Tests will be
performed, but not limited, to the
following substation components in a
timely schedule:
Protection
and Metering
- Current
Transformer ( CT ) test.
- Test for no
interconnection between DC circuits
or branches.
- Continuity,
polarity and burden test to all AC
secondary circuits.
- Complete
calibration and test to each
protective relay/device in all its
functions.
- Trip tests by
primary, secondary, back-up
protection and any other mechanical
protection.
- Local and remote
metering.
- Global functional
simulation of the protection and
control devices on the switchboards.
- Capacitor Bank
live unbalance alarm and trip tests.
- Perform live test
for bus differential protection trip.
- Final load tests
to all relays and meters.
Control and
Signaling
- Voltage Regulation
test.
- Transformer Tap
Changer Control test.
- Complete Signal
path tests.
- Synchronization
tests.
- Customized
Electrical Power Systems Operations-Maintenance
Training - All systems require
maintenance. Their performance will be
directly proportional to the care taken
to maintain it in optimum conditions. We
at IEG can help your company review,
update or develop maintenance/operations
procedures for your electrical,
mechanical and electronic systems and
train your personnel to perform the
operations and maintenance tasks.
Technical training objectives:
- Thorough
inspection of your electrical system.
- Evaluation of the
equipment manufacturer's recommended
maintenance and operations procedures.
- Update procedures
to your actual conditions.
- Prepare a
comprehensive maintenance and
operations course, specifically for
your system.
- Refreshing lessons
on electric theory (at engineering or
technical level).
- Refreshing course
on specific equipments operation
theory.
- Courses on
operations.
- Courses on
maintenance.
- Laboratory and
hands-on sessions using your system
and test equipment.
- Evaluation of the
training outcome.
- Project
Development and Project Management
- IEG can perform all the project
development services and its total
management. We at IEG have ample
experience developing projects from the
problem definition stage. IEG will help
you to carry project development
activities such as:
- Design
improvements to your system to meet
the actual and planned electrical
requirements.
- Definition of
design objectives.
- Identification of
constraints.
- Development of
construction specifications and a
request for proposal.
- Prepare
procurement specifications for
materials, equipment and abor
required.
- Evaluate proposals
and recommend the best alternatives.
- Aid your company
in negotiating the best price for the
required work.
- Technical contract
resolution.
- Supervision and
project acceptance.
- Supervision
and Inspection of Project Development
- IEG can provide supervision of the
development of your project and provide
certifications for payment of completed
portions. We can offer you a varied range
of supervision and inspection services to
satisfy your needs.
