We deliver a broad range of services that guarantee measurable results and a positive impact on your business.
Protection Philosophy
We assist in establishing a tailor-made protection philosophy in order to:
- Establish Minimum Requirement for Electrical
- Protection System
- Relay Setting Standards
- Specify Protection Equipment Standard
- Standardize Equipment for Critical Spares
- SCADA Network Data Protocol and Standards
Network Studies
Network studies using e-tap simulation software to do:
- Network Modelling
- Network Equipment Database
- Load Flow Studies
- Short Circuit Studies
- Contingency Analysis
- Grading / Coordination Studies
- Relay Settings
- Building a protection database
Network Studies (Continued)
Protection Coordination:
- Record Maximum Load Currents of Major Feeders
- Use of Nameplate Database
- Computer Aided Calculation of Minimum and
- Maximum Fault Levels

Field Services
In-Situ services:
- Consulting on new projects
- Fault and or failure investigations
- Onsite repairs of substation equipment
- Setup of recording equipment for planning or special investigations such as; Load Profiles, VARs and Power Factor and Harmonic Content
- Downloading of event reports from protection relays to do analysis and reports such as:
- * Fault reports
- * Motor Start-up Characteristic Reports
- * Sequence of Events Report
Field Services
Substation Protection evaluation of:
- Protection Schemes
- Protection Relays
- Current Transformers ( Primary and Secondary injection)
- Creating a Database of Relays and Current transformers in the Network
- Battery Tripping Units
Current Transformer (CT) testing
Primary injection testing of CT:
- Determines if the CT’s ratio is correct
- Determines if the CT’s polarity is correct
Secondary injection testing of CT's:
- Determines the health of CT’s magnetic core
- Determines the winding resistance of CT
- Determines the burden connected to the CT
Specialized Studies
Using specialized recording equipment and Network Modelling to do:
- Fault analysis
- Harmonic analysis
- Reactive power control
- Failure analysis
- Power Quality
Protection Relay Testing
Relay-tripping characteristic tests are done to determine if the replay trips within the specification
Training
We offer training from basic electricity to power system principles. Training courses are customizable and customer-specific.
Arc-Flash Protection Solutions:
Installation of arc flash sensors:
Detect fault within 2msec and depending on the
breaker speed (+ 35msec) clears the fault within
37msec
Protection Engineering & Design
- Design using world-class Protection standards and Philosophies
