Electrical Power System
Protection and Control, Coordination Analysis and Studies
- The reliability of your electric system is highly dependant on
its protection system. A miscalibrated 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.
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 labor
required.
Evaluate
proposals and recommend the best alternatives.
Aid
your company in negotiating the best price for the required work.
