The use of Traveling Waves (TW) in protection systems has grown significantly, driven by the need for faster responses, greater fault location accuracy, and the capability to operate on complex, hybrid lines or those with high Inverter-Based Resource (IBR) penetration. In this scenario, Conprove presents a complete solution that integrates technology, precision, and ease of use: the CE‑TW1.
In a video available on Conprove’s channel, Paulo Jr. demonstrates a comparative analysis between real waveforms and artificial waveforms—both with their own advantages and limitations. Based on this evaluation, Conprove developed a solution capable of uniting the best of both approaches, bringing robustness and high fidelity to traveling wave testing.

Real Waveforms vs. Artificial Waveforms: The Market Challenge
Historically, testing methods for Traveling Waves had limitations:
- Real Waveforms offer high fidelity but depend on actual fault records and do not always cover all scenarios of interest.
- Artificial Waveforms allow the simulation of countless cases but may lack the nuances present in real phenomena.
Conprove’s goal was to create a solution combining these two dimensions: the fidelity of the real wave with the flexibility and variability of the digitally synthesized wave.
CE‑TW1: The Best of Both Worlds
The CE‑TW1 is the equipment that materializes this proposal. Lightweight, portable, and highly versatile, it works in conjunction with Conprove test sets:
- CE‑7012
- CE‑6710
- CE‑6707
This integration allows for complete testing on:
- Traveling Wave-based protection relays
- Disturbance recorders
- Fault location algorithms
- Ultra-high-speed time-domain protection systems
Key differentiators of the CE‑TW1 include:
- Operational Versatility: Capable of applying single or multi-terminal methods without special adjustments.
- Total Waveform Fidelity: Precisely reproduces simulated voltages and currents, allowing for realistic tests.
- Ease of Use: Requires no complex configurations; simply integrate it into the test setup.
- Real Portability: Lightweight equipment designed for use in the laboratory, field, or commissioning.
Integration with PS Simul: Advanced Transient Simulation
The solution becomes even more powerful when combined with PS Simul, Conprove’s software for power system modeling and electromagnetic transient simulation. It allows you to:
- Simulate faults in different topologies
- Model lines, transformers, and real system conditions
- Export waveforms directly to the CE‑TW1
- Generate unlimited scenarios for comprehensive testing

Why is this solution so important?
Protection based on Traveling Waves represents the new frontier in protection engineering, offering:
- Superior fault location accuracy
- Extremely fast actuation speed
- Reliability in hybrid systems, cables, and compensated lines
- Better performance in systems with high penetration of inverter-based resources (IBRs)
The CE‑TW1 enables complete testing of these functions, ensuring operational compliance and safety.
