Stronger Power Grids. Greater Confidence.
Our mission: extend transformer life and prevent catastrophic failures that can cost tens of millions and jeopardize public safety.
Since pioneering some of the first online bushing monitors, we’ve advanced transformer monitoring and predictive analytics so utilities can act with confidence before problems escalate. With thousands of systems deployed worldwide, we’re trusted by utilities and OEMs alike.
Experienced Transformer Monitoring.
ZTZ Services protects critical transformers in diverse settings—from mountain resorts to solar farms and power plants. Our bushing monitors have helped utilities safely re-energize transformers, track insulation health, and avoid costly outages.
By delivering proven condition-based strategies that outperform offline testing, we reduce maintenance costs while ensuring grid reliability.
Innovative Power Grid Data Management.
Our advanced data analysis methods—such as phasor-based algorithms and adjacent phase detection—spot insulation defects well in advance of failure. By combining bushing monitoring, DGA monitoring, and trend analysis, we provide actionable alarms that replace calendar-based maintenance with real-time, automated protection.
We turn complex signals into clear insights.
Single Focus, Proven Results.
ZTZ Services is dedicated solely to transformer asset health. Our U.S.-made hardware is utility-grade, cybersecure, and built to last decades without recalibration. From bushing monitors to DGA monitors, every system component integrates seamlessly with existing fleets and is backed by 24/7 service.
Each “transformer save” we deliver strengthens our reputation as the trusted partner in reducing operational risk and preventing unplanned outages.
Active Transformer Monitoring Solutions
ZTZ Services delivers a full process for transformer health management—not just daily readings.
- Gather Data – Continuous inputs from bushing taps, DGA sensors, and CCVT monitors.
- Process Data – Patented algorithms track power factor, capacitance, and gas trends.
- Engineer Review – Skilled engineers separate normal aging from developing problems.
- Action Plan – Clear maintenance guidance to address issues early.
ZTZ Services Power Grid Monitoring Products
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.
