Verified customer deployment
Voltage Sag Ride-Through for Critical Textile Texturing Machines
Chemical Fiber Manufacturer, Fujian, China
Two WS300 systems protect eight large texturing machines. Results below are limited to verified backend records reported through August 24, 2026.
Answer first
Short Answer
WS300-66, installed in June 2026, protects 4 large texturing machines. Its backend recorded 13 voltage-sag records and 13 successful ride-through records through August 24, 2026.
WS300-67, installed in July 2026, protects 4 additional large texturing machines. Its backend recorded five voltage-sag records and five successful ride-through records through August 24, 2026.
These are separate system records. They must not be described as 18 independent plant-level voltage-sag events because the same grid disturbance may be recorded by both systems.
The production risk
Brief grid events were stopping critical textile production
Large chemical-fiber texturing machines depend on coordinated drives and auxiliaries. At this Fujian facility, voltage sags could stop production equipment even when the grid disturbance itself was brief. Wilson Technology implemented the project in two verified deployment stages.
First deployment
WS300-66 · June 2026
WS300-66 was installed in June 2026 to protect four large texturing machines. Through August 24, 2026, its backend contained 13 voltage-sag records and 13 successful ride-through records.
During one documented severe voltage-sag occurrence, the four protected machines continued operating while multiple unprotected loads stopped, including ventilation equipment. No unverified sag depth, duration, power rating, or electrical topology is asserted here.
Expanded protection
WS300-67 · July 2026
A second system, WS300-67, was installed in July 2026 to protect another four large texturing machines. Through August 24, 2026, its backend contained five voltage-sag records and five successful ride-through records.
Together the two systems cover eight machines, but the verified record counts remain system-specific and are not combined into a claim about independent plant events.
Verified results
Backend records by system
| System | Installed | Protected load | Backend sag records | Successful ride-through records |
|---|---|---|---|---|
| WS300-66 | June 2026 | 4 large texturing machines | 13 | 13 |
| WS300-67 | July 2026 | 4 large texturing machines | 5 | 5 |
Evidence boundary
What this case establishes—and what it does not
This case provides verified field evidence that the two installed systems maintained their respective protected texturing-machine groups through every voltage-sag record in each system's backend dataset up to the stated cutoff date.
It does not publish or imply the equipment power rating, voltage sag depth, sag duration, ROI, customer company name, detailed electrical topology, or certification status. Those items have not been verified for public release.
