Megger MCT1605

The Megger MCT1605 stands as a premier, field-ready, and highly automated testing instrument specifically engineered to diagnose, verify, and commission current transformers (CTs). As electrical power grids grow more complex, maintaining the absolute integrity and precision of protection and metering CTs becomes paramount. The MCT1605 provides substation technicians, electrical engineers, and commissioning teams with an all-in-one platform capable of evaluating CT performance under rigorous field conditions.

By integrating multi-functional testing capabilities into a single ruggedized enclosure, the Megger MCT1605 eliminates the need for multiple bulky instruments. It delivers exceptionally accurate results for CT ratio testing, saturation characteristics, polarity validation, winding resistance, and insulation parameters in a minimal amount of time. Whether you are conducting routine maintenance at an industrial plant or executing large-scale commissioning at a high-voltage substation, the MCT1605 ensures your protective relays and meters receive flawlessly accurate data from your current transformers.

Advanced Ratio Testing and Core Functionality

The core strength of the Megger MCT1605 lies in its sophisticated Current Transformer Ratio Testing mechanism. Unlike traditional manual methods that require tedious setup adjustments and constant monitoring, the MCT1605 utilizes an automated voltage injection method to precisely measure the turns ratio and voltage ratio of the CT under test.

When executing a ratio test, the instrument simultaneously checks the phase deviation and polarity of the transformer. This ensures that the primary and secondary windings are oriented correctly, preventing critical protection misoperations during real-world fault conditions.

Furthermore, the instrument excels at handling multi-ratio CTs. With its advanced simultaneous multi-tap testing feature, technicians can connect up to five taps at one time. The MCT1605 will then automatically cycle through every single combination, measuring all ratios, polarities, and knee points sequentially without requiring the operator to manually swap test leads at the top of a transformer or switchgear cabinet. This drastic reduction in physical intervention minimizes human error and shortens testing times from hours to mere minutes.

Key Features and Technical Advantages

• Fully Automated Test Sequences: With a single press of a button, the Megger MCT1605 initiates a comprehensive suite of tests. It automatically ramps the voltage to determine the saturation curve, identifies the exact knee-point, measures winding resistance, checks the ratio, and verifies polarity.

• Exceptional Measurement Accuracy: Engineered with top-tier measurement circuitry, the Megger MCT1605 boasts a typical ratio accuracy of pm 0.05%. This extreme precision makes it fully capable of testing high-accuracy metering-class CTs as well as heavy-duty protection-class CTs.

• High Voltage Saturation Testing: The device can output up to 2000V to accurately locate the knee-point on excitation curves, complying fully with both IEEE and IEC international standards.

• Graphic Real-Time Excitation Curves: The integrated high-resolution color display plots the CT excitation and saturation curves in real-time. This immediate visual feedback allows engineers to diagnose core degradation or shorted turns directly on-site.

• Uncompromising Field Safety: Operator safety is integrated into the foundation of the MCT1605. The system features an automatic ground-verification circuit, high-voltage warning indicators, and a dedicated emergency stop switch to safely discharge energy from inductive loads.

• Rugged, Built-for-Field Enclosure: Housed in an impact-resistant, weatherproof transport case, the entire unit is lightweight and highly portable, built to withstand the punishing environments of open-air utility substations.
