At Twiga Cement’s Wazo Hill facility, one of Tanzania’s largest cement manufacturing sites, unexplained motor shutdowns, lost production hours, and disputes with the national utility were common and costly. With medium-voltage motors driving critical processes, even a short disruption meant hours of lost output and revenue.
A Unilyzer 900 was deployed to capture detailed electrical performance data throughout their medium-voltage network and at their utility interface. Key findings in brief were:
- Pinpointed the source of electrical disturbances
- Time-stamped, standards-compliant data made discussions with utility fact-based and constructive
- Utility used the data to fine-tune feeder protection, preventing unnecessary plant trips
- Optimized protection settings allowed 11 medium-voltage motors to ride through harmless disturbances
Reduced downtime translated to significant production gains and profitability. ROI was immediate, payback period estimated under 3 months.
“With the Unilyzer 900, we moved from assumptions to facts. We reduced nuisance motor trips, improved coordination with the utility company, and gained real production reliability. This is not just a tool – it’s an investment in uptime and peace of mind.” Said Eng. Kassim Khalfan K.
