About ZTZ Services International

ZTZ Services has been helping utilities protect their power grids for more than 25 years. We design, manufacture, install, and maintain advanced transformer monitoring systems that give utilities real-time visibility into the health of their high-voltage and medium-voltage assets. Where most transformers receive only a single lab sample each year, ZTZ brings continuous monitoring, turning one data point into thousands. Our systems help utilities catch more than 95% of incipient faults before they escalate, reduce catastrophic failure risk, and extend transformer life. Many of the utilities we serve have trusted us for decades, relying on our monitoring expertise to keep their fleets performing safely and predictably. All ZTZ hardware is engineered and manufactured in-house in North Miami, Florida, and built to operate reliably for decades in demanding environments. As a Siemens OEM manufacturing partner, we combine deep industry knowledge with proven technology to deliver monitoring solutions that integrate seamlessly with existing utility systems. Our monitoring portfolio includes bushing monitoring, CCVT monitoring, dissolved gas analysis (DGA), partial discharge detection, and fully integrated transformer health software. We support every installation with hands-on service, ongoing maintenance, and expert data analysis. Utilities gain clear transformer health ratings, historical trends, and real-time alerts that enable smarter maintenance planning, improved safety, and stronger operational confidence. Our mission is simple: help utilities prevent transformer failures, avoid costly outages, and protect the stability of the grid.
