Megger MRCT — Relay and Current Transformer Test Set

The Megger MRCT is a lightweight, robust, portable unit used to perform demagnetisation, ratio, saturation, winding resistance, polarity, phase deviation, and insulation tests on current transformers. It can also be configured to test instrument voltage transformers (VTs), capacitive voltage transformers (CVTs), and single-phase relays.

The MRCT simplifies testing by automatically calculating ratio errors, saturation curves, and knee points. Its patented simultaneous multi-tap measurement system reduces testing time by up to 20% on multi-tap CTs. With one button press, the unit connects directly to multi-ratio CTs and performs all tests — saturation, ratio, polarity, winding resistance, and insulation — on all taps without changing leads. Results are displayed during testing and a report is generated automatically upon completion.

The unit features an integrated 8.5-inch TFT LCD full-colour touchscreen (STVI — Smart Touch View Interface) with wide viewing angle technology for use in direct sunlight, a rotary amplitude control knob, and an emergency stop button. It can also be controlled via a laptop using Megger's PowerDB software.

Key Features:
• Industry-leading test duration using patented simultaneous multi-tap measurements — reduces testing time by 20% on multi-tap CTs
• Ratio accuracy up to ±0.1% — supports testing of both metering and protection class CTs
• Integrated single-phase relay test system
• Grouped testing: demagnetisation, knee points, ratios, saturation curves, winding resistance, insulation and more
• Measure all ratios and saturation curves on multi-tap CTs with one lead connection
• Optional DC excitation technique for testing CTs with knee points up to 30 kV
• Optional integrated VT and CVT test system
• Automatic report generation via onboard STVI or PowerDB Lite software
• Can simultaneously display up to 10 CT saturation curves
• Knee point calculation compliant with IEEE C57.13.1, IEC 60044-1, IEC 60044-6, and specialised CT types (PX, TPS, TPX, TPY, TPZ)
• Tested to US Department of Defense standards for impact, vibration, and temperature
