Energy Management
Thermographic Imaging
Our thermal imaging looks at electrical equipment, control panels, cables, components that are hotter or cooler than similar ones under similar loads. Our electrical professionals performing thermal imaging can identify the following:
- Broken and undersized wires
- Faulty (too loose, over tightened or corroded) connection
- Electrical unbalance during phases and defective insulation
- Overheated equipment, panels and components
Power Quality Analysis
Power Quality has to do with the extent to which the delivery and utilization of electric power affects the performance of electrical equipment and loads. Our power quality monitors will detect and record the 7 types of power quality problems.
- Transients
- Interruptions
- Sag/Under Voltage
- Swell/Over Voltage
- Waveform Distortion
- Voltage Fluctuations
- Frequency Variations
These disturbances create technical challenges such as, loss of production and revenue, process interruptions and damage to equipment, higher energy costs, and loss of data. Our job is to perform test works that will reveal the real causes of your power system disturbances and propose solutions that will make your parameters fall within acceptable limits as per below requirements.
Parameters |
Compliance Limits According to EN50160: 2001 |
Frequency |
Must remain between 49.5 (-1%) and 50.5 (+1%) Hz. |
Supply Voltage |
The voltage must be between 90% and 110% of nominal voltage. |
Voltage unbalance |
The negative sequence cannot assume a magnitude higher than 2% of the direct sequence |
Harmonic voltage |
Harmonic voltage: THD < 8 %, 3rd < 5.0%, 5th < 6.0%, 7th < 5.0% |
Energy Audit
Electric motor systems are by far the most important type of load in industry, using about 70% of the consumed electricity. We analyse motor starting methods for electric motor-driven loads and propose solutions to save energy cost. Our audit service cover the entire motor applications and market segments.
Protection Coordination Study
The goal of this study will be to coordinate the settings of the whole phase and earth protective scheme in order to ensure the selectivity of the medium and low voltage network. The selectivity study takes particularly take into account:
- The results of the short-circuit study
- The operating modes of the network
- The setting of the protection installed upstream from the factory installation: on the 11kV side.
- The setting of the protections installed downstream: that protection installed on LV feeders.
Scope of data required for the study included all upstream, downstream, and load list as follows
- Electrical Network Data
- Cables Data
- Load Types and List
- Upstream Protection setting
- Transformers data sheet
- Motors
The report of the study will bring out pertinent protection settings required as standards based on the network and propose recommended settings as follows:
- Network and operating modes description
- Hypothesis for fault detection and elimination, and selectivity
- Maximum and minimum short-circuit currents taken into account
- Selectivity graphs needed for coordination understanding
- Relays settings table
