Based in Miami, Florida, ZTZ Services has led the way in high- and medium-voltage transformer monitoring technology for decades. Our reputation is built on reliability, innovation, and an unwavering commitment to preventing power grid failures.
Unlike other providers, we design and manufacture our own hardware, develop our own software, and provide installation, training, and service solutions. ZTZ Services’ bushing and CCVT monitors are proudly made in the USA, backed by a lifetime warranty, and built to utility-grade standards. Secure, tariff-free, and proven in the field, they deliver crucial data you can count on.
One out of every 200 transformers experience a major failure every year. Bushings account for 37% of catastrophic transformer failures.
When transformers fail, the downstream consequences can shut down entire power grids. With 3-plus-year lead times for replacement, prevention is critical.
Despite severe failure risks, half of HV/MV transformers lack continuous monitoring, relying on annual testing that misses critical changes.
Dedicating resources for regular physical inspections is expensive and distracts from fleet maintenance.
Weather, power surges, and increasing loads affect transformers on utility networks differently. However many signs of aging are the same: energy spikes or trace gases in transformer oil indicate sealing or insulation breakdown.
Monitor insulation degradation, moisture ingress, and mechanical failures in transformer bushings.
Advanced DGA monitoring detects gas formation in transformer oil, identifying insulation breakdown and potential arcing before critical failures occur.
The CCVT MAX identifies issues like loose connections, capacitor failures, and ferro-resonance problems before they escalate.
Combines DGA and bushing data using advanced algorithms built on decades of proven experience. Sends secure alarms to SCADA platforms.
ZTZ Services handles all aspects of installation and ongoing service. Count on our engineers to ensure optimal monitor performance and minimal disruption to your operations.
ZTZ Services pioneered the first on-line bushing monitoring systems in the US market and advanced CCVT health analysis decades before the competition.
We understand the real-world life of transformers. With millions of trend data points and deep experience, we deliver the insight needed to detect and prevent power grid failures..
ZTZ premium USA made hardware stands up to the test and will outlast the rest. Our technicians keep sensors reliable and the data flowing.
Active transformer monitoring transforms data depth from one sample a year to eight samples a day.

In the power industry, silence isn’t stability — it’s often risk building in the background. A transformer can run “quietly” for months while insulation breaks down, hotspots develop, and dissolved gases rise. Then one day, without warning, it fails — and the cost of that silence hits all at once.
Utility grid automation isn’t just a buzzword—it’s the most effective path to preventing costly disruptions and securing long-term energy reliability. As electricity demand rises and infrastructure ages, the need for resilient, intelligent grids has never been greater. A review of the top energy stories of 2025 makes one thing clear:
Within power asset management, Dissolved Gas Analysis (DGA) of transformer oil serves as an indispensable diagnostic tool. Combined with partial discharge and bushing monitoring, it is the closest we get to listening to the internal health of these vital assets. However, merely conducting DGA isn’t enough; the real power lies
