Trusted by utilities worldwide.
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.
Transformer monitoring is all we do.
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.
Real solutions. Real-time.
One out of every 200 transformers experience a major failure every year. Bushings account for 37% of catastrophic transformer failures.
Catastrophic transformer failures cost up to $30MM.
When transformers fail, the downstream consequences can shut down entire power grids. With 3-plus-year lead times for replacement, prevention is critical.
50% of transformers are inspected on-site once a year.
Despite severe failure risks, half of HV/MV transformers lack continuous monitoring, relying on annual testing that misses critical changes.
Physical inspection drains resources.
Dedicating resources for regular physical inspections is expensive and distracts from fleet maintenance.
Transformers age unpredictably.
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.
Comprehensive active transformer monitoring solutions.
Bushing Monitoring
Monitor insulation degradation, moisture ingress, and mechanical failures in transformer bushings.
Dissolved Gas Analysis
Advanced DGA monitoring detects gas formation in transformer oil, identifying insulation breakdown and potential arcing before critical failures occur.
CCVT Monitoring
The CCVT MAX identifies issues like loose connections, capacitor failures, and ferro-resonance problems before they escalate.
TraMos Software
Combines DGA and bushing data using advanced algorithms built on decades of proven experience. Sends secure alarms to SCADA platforms.

The Staggering Reliance on Transformers in Global Industry
When you run only a handful of critical HV/MV units, there is little to no redundancy. Taking one offline can idle an entire site, halt production, or interrupt essential services. The industries that depend on these assets are not peripheral.
The Effect of Renewables on the Power Grid: Part 3
Standard dissolved gas analysis (DGA) and bushing interpretation methods were developed under conventional loading assumptions that no longer fully match today’s grid conditions. We present three questions that illustrate key evolving relationships between current IBR operating conditions and transformer monitoring data.
