Description
PD90-2 / PDTD90-2 – Diagnostic system for medium- and high-voltage cables
PD90-2 and PDTD90-2 are advanced diagnostic systems that offer both portable and integrated solutions for analysis of medium- and high-voltage cables, rotating machines, and transformers. The systems enable early detection of weaknesses, creating better conditions for preventive maintenance and reducing the risk of costly downtime.
Efficient and Time-Saving Diagnostics
PDTD90-2 is equipped with integrated Tan Delta technology, enabling simultaneous measurement of partial discharge (PD) and Tan Delta (TD). This parallel diagnostics saves time and eliminates the need for cable preconditioning, which could otherwise negatively affect measurement results.
The system also enables measurements at constant frequency across different cable lengths, which is essential for comparing results from previous tests and monitoring development over time.
Flexible System with High Precision
The diagnostic system is designed for testing XLPE, PE, EPR, and PILC cables up to 100 km. With precise fault localization of up to 1% accuracy and a resolution of 0.1 pC per 0.1 meter, even small deviations can be detected at an early stage.
In combination with the HVA90 unit, a complete and powerful system for cable testing up to 90 kV is created, making the solution both scalable and adaptable to different needs.
Benefits in Practice
- Simultaneous PD and Tan Delta diagnostics in one system
- Stable sinusoidal output voltage with consistent frequency
- Accurate localization and analysis of partial discharges
- Effective noise suppression and high measurement precision
- Tailored software for analysis and reporting
Technical Capabilities
- Operating voltage: up to 90 kV peak / 64 kV rms
- Capacitance: approx. 1 nF (coupling capacitor and filter)
- Velocity range: 10–150 m/µs
- PD background level: <10 pC
- Samplingshastighet: 250 MS/s
- Sampling rate: 250 MS/s
Standards and Reliability
PD90-2 and PDTD90-2 comply with relevant international standards and guidelines, including IEEE 400.2 and 400.3 as well as IEC 60270, IEC 60502-2, HD 620 and CEI EN 50393. This ensures reliable and reproducible measurement results in all types of projects.
An Investment in Reliable Operation
With PD90-2 and PDTD90-2, you get a powerful diagnostic system that improves the reliability of your cable systems. By identifying issues at an early stage, you can reduce the risk of downtime, optimize maintenance, and extend the lifespan of your equipment.
