- No-trip earth loop impedance test with low and extra-low test current modes
- RCD contact voltage indication
- Prospective Earth Fault Current (PEFC) display
- Voltage harmonics up to the 49th
- THD% (Total Harmonic Distortion) measurement
- Results storage for 64 loop and RCD tests
- Dedicated app – Megger MPCC230 Pro Circuit Checker
Volt and Socket Test:
The Megger MPCC230 performs a simple socket check with True-RMS voltage output, alerting users if a socket is correctly wired and the touch voltage is below 50 V. It provides clear warnings for wiring faults such as:
- Phase - Neutral Reverse
- Earth Reverse
- Open Neutral
- No Earth
- Touch Voltage >50V
RCD Testing:
The Megger MPCC230 allows testing of Type A, AC, and F RCDs at 30 mA, as well as an AUTO test at x½, x1, x5 at 0° and 180° with a single button press.
- Loop Testing on TT and TN Systems
- Measures Earth Resistance (Ω) and Touch Voltage (V)
- Tests Impedance Zs (Z L-Pe) (Ω) and IPEFC Prospective Earth Fault Current
- Standard test current: 15 mA
- Advanced low current test (6 mA) for systems with leakage currents that may trip the RCD
Harmonics Analysis:
The Megger MPCC230 provides advanced fault-finding capabilities, displaying:
- Fundamental harmonic and frequency (~50 Hz)
- THD% (Total Harmonic Distortion) of voltage supply
- Individual harmonics up to the 49th, allowing for in-depth frequency analysis
Memory Storage and Reporting:
The Megger MPCC230 automatically saves RCD and LOOP test results, storing up to 64 measurements in chronological order for easy filtering and recall. Results can be downloaded to a mobile device via the free MPCC Link app, available on the Apple App Store and Google Play Store.
