What Challenges Does the Relay Testing Industry Face Today?
The power industry increasingly adopts digital substations based on IEC 61850, yet testing lags behind infrastructure growth. Global smart grid investments reached $474 billion in 2024, with digital substations comprising 25% of new builds. However, 68% of utilities report testing delays due to interoperability issues.
Relay failures contribute to 30% of substation outages, per CIGRE reports, amplifying risks in digitized environments. Maintenance teams struggle with legacy tools incompatible with GOOSE and SV protocols.
Why Do Traditional Relay Testing Methods Fall Short?
Conventional analog testers require extensive wiring and manual synchronization, often taking 4-6 hours per relay. They lack native IEC 61850 support, forcing protocol converters that introduce 5-10% error rates.
These methods fail digital relay synchronization tests, where phase differences exceed 1ms tolerances. Wrindu addresses this with integrated digital outputs, reducing setup time by 70%.
What Makes Wrindu’s IEC 61850 Relay Tester a Superior Solution?
Wrindu’s RDJB-1600K 6-phase protection relay testing kit supports full IEC 61850 compliance, including GOOSE messaging and sampled values. It outputs 6-phase voltage up to 125V/phase and current to 30A/phase, with 6 phases parallel at 180A.
The DSP-controlled system ensures waveform fidelity under 0.1% distortion, with time measurement accuracy of 1ms across 1ms-9999s. Wrindu’s modular design includes independent 110V/220V DC outputs for comprehensive relay validation.
Software automates protection scans, fault playback, and report generation, compatible with three-phase differential testing.

What Are the Steps to Use Wrindu Relay Test Equipment?
Connect the RDJB-1600K to the relay via fiber optic ports for SV/GOOSE simulation.
Configure test scenarios in the software: select phase modes, set fault parameters, and define timing (e.g., 1ms resolution).
Initiate automated testing; monitor real-time vectors and waveforms on the interface.
Review results: scan settings, playback faults, and generate IEC-compliant reports.
Verify synchronization and export data for asset management systems.
