Voltage Sag Protection for Factories in Egypt
Factories in Egypt experiencing voltage sag-related trips should begin with synchronized measurement at the point of common coupling and the sensitive production load.
Regional context
Measure the site before selecting protection.
EEHC publishes a feed-quality improvement page that references Voltage Sag Compensators for certain industrial subscribers and power-quality measurement for subscribers affected by other loads on the same loop. This is useful public context, not a substitute for the applicable utility requirements, contract terms, or site study.
Industrial zones differ in supply topology, feeder exposure, plant load mix, and operating practices. Wilson Technology should confirm the local utility interface and project obligations with the customer and qualified Egyptian parties.
Priority applications
Industrial sectors and assessment areas.
| Industry / area | Typical assessment focus | Public engineering position |
|---|---|---|
| Textile | VFD trips, tension/process sequence, air and chilled-water auxiliaries | Site-specific engineering assessment |
| Plastics | Extrusion drives, heaters, cooling, material loss after stop | Site-specific engineering assessment |
| Chemical / petrochemical | Pumps, compressors, cooling, lubrication, process safety | Site-specific engineering assessment |
| Steel | Large drives, process sequence, auxiliaries, feeder behavior | Site-specific engineering assessment |
| 10th of Ramadan / 6th of October / Sadat / Borg El Arab | Site supply, PCC exposure, local service and access | Project-specific local coordination |
Protection boundary
Select the architecture from the actual load mix.
Voltage-sag protection architecture should be selected from the actual load mix and disturbance profile. For VFD-heavy factories with accessible DC links, direct DC-bus support may be efficient. For mixed sensitive loads or production feeders that must remain energized together, a Dynamic Voltage Restorer (DVR) can be evaluated as a whole-line protection option.
Assessment path
Coordinate measurement, design, and local implementation.
- Remote intake: load, voltage, one-line, trip records
- Agree local site access and qualified measurement scope
- Record PCC and sensitive-load events
- Correlate VFD / PLC / process timestamps
- Compare DC-bus, whole-line, UPS, and hybrid options
- Confirm local compliance, service, and acceptance testing
