We offer the following range of services
Power Quality & Load Analysis
- Investigate unknown breaker/relay trip issues or equipment damages (overloading, earth fault / leakage problems)
- Power Quality monitoring – compliance check on quality of supply against local or international standards
- Assess / check on level of harmonics in electrical system (harmonics measurement test report).
- Power quality impact studies (adding on more non-linear loads?)
- Analysis of Power Quality Data (you perform the actual physical measurement, we analyze the data for you)
- Power Quality reports for submission to SP PowerGrid (pre and post distributed generation / Solar PV connection measurements)
- Voltage dip Vulnerability Assessment (How vulnerable is your plant to voltage dips?)
- Assessment on existing loading profile (Capacity for expansion? Are loads distributed equally across phases? Inrush loads?)
Protection Coordination & Arc Flash Studies
- Ensuring during an abnormal power flow (electrical fault), protective devices react to isolate the problem with minimum disruption to the rest of the system
- Fault current analysis, incident energy modelling and calculation, equipment evaluation, arc flash labels
Earthing & Lightning Protection
- Investigate earthing or lightning protection related problems
