List of Relay Protection Tester Models

Relay protection testers are specialized devices used to verify the correct operation of protective relays under simulated fault conditions, with examples including RDJB-1600M, ARTES 600, Mentor 12, and RELAYSTAR-H60.

Key Examples

Wrindu RDJB-1600M: A multifunctional relay tester suitable for substations, utilities, and industrial power systems. It supports flexible multi-phase output, high-current injection, and advanced differential protection analysis. The device features high-fidelity linear power amplifiers for stable waveforms and intelligent DSP control for precise testing.

ARTE

S 600: A compact and universal solution for testing all types of protection relays, including electromechanical, static, and IEC61850 digital relays. It combines a protection test set and universal calibrator in one device, enabling both type and field testing. Mentor 12: An advanced three-phase relay test set designed for type and field testing of electromechanical and digital relays.

It is suitable for comprehensive testing in modern substations and supports multi-phase injection. RELAYSTAR-H60: A portable 6-phase protection relay test system capable of testing most modern multi-function relays. It allows closed-loop testing and simulation of low-level outputs for digital relay inputs.

DD

G Primary Current Injector Test Set: Designed for high-current testing, CT calibration, and temperature-rise testing. It is particularly useful for testing high-burden electromechanical relays.

Applications and Features

Relay protection testers are used to: Verify relay operation under overcurrent, overload, short circuit, voltage fluctuation, and frequency abnormalities. Test all generations of relays, from electromechanical to microprocessor-based digital relays. Perform primary and secondary injection testing, type testing, commissioning, and maintenance.

Simulate real fault conditions to ensure accurate trip timing and protection performance, improving grid reliability and safety. These testers are essential for utilities, industrial power systems, and substations to maintain reliable operation, prevent equipment damage, and ensure compliance with standards such as IEC 60255 and IEEE C37. 90.
