Relay testers are designed with advanced functionalities to efficiently test multiple relays at the same time. This capability ensures faster testing processes and accurate results for complex protection schemes.

1. Multi-Channel Capability

• Modern relay testers include multiple voltage and current output channels, allowing independent control for each relay.
• Channels can simulate different scenarios for multiple relays in parallel.

2. Independent Control

• Each relay is tested under its unique settings and fault conditions without interference.
• Control software allows configuring and managing multiple relays simultaneously.

3. Automated Sequencing

• Testers can execute automated sequences, cycling through relays without manual intervention.
• Test parameters, such as fault current or voltage levels, are applied automatically.

4. Real-Time Monitoring

• Simultaneous real-time feedback ensures all relays are tested within their parameters and responses are logged instantly.
• Any anomalies are flagged during the test.

5. Data Logging for Multiple Relays

• Comprehensive logging ensures results for each relay are stored separately for analysis.
• This allows for accurate comparison and trend monitoring.

6. Distributed Testing

• Some systems integrate multiple testers, allowing testing of geographically dispersed relays from a central control unit.

• Distributed systems can communicate test results in real time.

Relay testers streamline the process of handling multiple relays by leveraging multi-channel outputs, automation, and sophisticated software, ensuring efficiency and precision in protection relay testing.
