Answer first
Short Answer
Factories in Egypt experiencing voltage sag-related trips should begin with synchronized measurement at the point of common coupling and the sensitive production load.
The Egyptian Electricity Holding Company (EEHC) publicly discusses voltage sag compensators and measurement for affected subscribers, but each factory still needs a site-specific protection boundary and technical review.
Wilson Technology's V1 page offers an engineering assessment pathway; it does not claim a completed Egypt customer project, local certification, office, or partner.
When This Applies
- A factory experiences repeated VFD, PLC, compressor, pump, or production-line trips during short grid disturbances.
- The plant needs to distinguish source-side sag exposure from internal voltage drop or process-side faults.
- A new or existing facility is evaluating a Voltage Sag Compensator (V.S.C.), DVR, DC-bus support, UPS, or hybrid solution.
- The project needs a measurement package and local coordination before equipment selection.
Egypt Industrial Grid Context
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 Industries and Areas
| Industry / area | Typical assessment focus | V1 status |
|---|---|---|
| Textile | VFD trips, tension/process sequence, air and chilled-water auxiliaries | Engineering focus; case data pending |
| Plastics | Extrusion drives, heaters, cooling, material loss after stop | Content expansion planned |
| Chemical / petrochemical | Pumps, compressors, cooling, lubrication, process safety | Engineering focus; case data pending |
| Steel | Large drives, process sequence, auxiliaries, feeder behavior | Content expansion planned |
| 10th of Ramadan / 6th of October / Sadat / Borg El Arab | Site supply, PCC exposure, local service and access | Local partner/service model pending |
Local Assessment Path
1. Remote intake: load, voltage, one-line, trip records2. Agree local site access and qualified measurement scope3. Record PCC and sensitive-load events4. Correlate VFD / PLC / process timestamps5. Compare DC-bus, whole-line, UPS, and hybrid options6. Confirm local compliance, service, and acceptance testingLimitations / When Not to Use
- Do not present an engineering example as an Egypt customer case.
- Do not infer EEHC, utility, government, or local partner endorsement.
- Do not fix equipment ratings before receiving site voltage, load, waveform, and duration data.
- Do not omit local electrical, import, certification, installation, and service requirements from project planning.
Recommended Architecture
Start with a 30-day measurement plan when event frequency supports it, then protect the smallest boundary that preserves production. For accessible critical drives, evaluate VFD DC-bus support; for mixed-load feeders, evaluate whole-line restoration; for near-zero or longer interruptions, include an energy source sized to the full interval.
