About Megger RCD Testers
Megger RCD (Residual Current Device) testers are instruments designed to evaluate the functionality and safety of RCDs within electrical installations. RCDs are crucial for protecting individuals from electric shocks by detecting and disconnecting circuits when an imbalance between live and neutral currents occurs. Regular testing with devices like Megger's RCD testers ensures these protective mechanisms operate correctly, maintaining electrical safety standards.
Key Functions
- Trip Time Testing: Measures the time it takes for an RCD to disconnect the circuit upon detecting a fault, ensuring it operates within specified safety parameters.
- Trip Current Testing (Ramp Testing): Determines the exact current level at which the RCD trips, verifying its sensitivity and proper calibration (Megger RCDT320 and above).
- Auto Testing Sequences: Performs a series of tests automatically, including multiple trip time and current assessments, streamlining the verification process (Megger RCDT320, RCDT330 and LRCD220).
- Testing of Various RCD Types: Accommodates standard, Type A, selective, and programmable RCDs, ensuring comprehensive testing across various installations.
- Combined Testing: Loop and RCD testing in one unit (LRCD series)
