Transmax 2000 Bushing Monitor with Partial Discharge (PD)
A unified bushing monitor platform.
The TRANSMAX 2000 is an all-in-one system for active bushing and partial discharge monitoring. It goes beyond standard bushing checks to give deeper maintenance insight. Using advanced signal processing, it tracks PD activity (.1–20 MHz), load current, temperature, humidity, and geomagnetically induced currents (GIC). The result is a complete, real-time view of transformer health.
- Spots the earliest signs of bushing failure using standard diagnostic methods and partial discharge detection.
- >95% incipient fault detection rate with the lowest false positive rate in the industry.
- Reduces site visits by approximately 66% in targeted maintenance jobs.
One connection. Total transformer insight.
Simplified installation and maintenance.
A single bushing sensor handles both PD and power factor monitoring—no extra coils, no added complexity. This unified approach lowers installation cost, reduces wiring and potential failure points. Supports standard SCADA utility communication protocols (Modbus, DNP3.0, IEC 61850).
Accurate and actionable data.
The TRANSMAX 2000 tracks key transformer parameters, including load current on up to three phases, transformer and hot-spot temperatures, ambient temperature and humidity, and GIC levels. This wide coverage links multiple stress factors for stronger predictive diagnostics.
Seamless electric grid integration.
TRANSMAX 2000 natively supports Modbus, DNP 3.0, and IEC 61850 protocols for immediate SCADA compatibility. ZTZ Services developed TraMoS software provides real-time visualization without third-party tools.
The TRANSMAX 2000 is purpose-built to help utilities prevent catastrophic transformer failures under the demanding conditions of the modern power grid. Its advanced monitoring capabilities make it ideally suited to detect bushing failures at:
- Solar generation facilities
- Wind power installations
- Data center substations
- Power generation plants
- Distribution substations
- High-voltage transmission substations
