Megger MOM200A Micro Ohmmeter

The MOM200A™ is designed to check and measure contact resistances in high-voltage circuit breakers, disconnecting switches (isolators) and busbar joints. The instrumen is an excellent choice when 200 amperes or less are needed for measurement.Since the MOM200A weighs only about 14 kg (31 lbs), it’s conve-nient to take along with you. MOM200A is ideal for finding poor connections since it can put out 100 A for extended periods. Its range extending up to 20 milliohms makes it ideal for measuring many different types of connections.A complete MOM200A includes a cable set (including separate sensing cables) and a transport case.

Megger MOM200A Micro Ohmmeter Key Features:

The Megger MOM200A Micro Ohmmeter is a specialized instrument designed to deliver precise and reliable resistance measurements, particularly suited for the testing of high voltage circuit breakers, disconnecting switches (isolators), and busbar joints. This device exemplifies efficiency and precision in situations where a maximum of 200 amperes is required for specific measurements, offering a practical solution for comprehensive electrical maintenance and testing.

  • 200 Ampere Capability: The MOM200A can deliver up to 200 amperes, making it powerful enough for most applications that require detailed analysis of contact resistance. This level of current is particularly effective for identifying issues in high voltage electrical connections and components.
  • Lightweight and Portable: Weighing only about 14 kg (31 lbs), the MOM200A is exceptionally portable. This lightweight design makes it easy to transport, especially to and within challenging and difficult-to-reach locations where traditional heavier equipment may be impractical.
  • Extended Current Output: The instrument can sustain an output of 100 amperes for extended periods. This feature is crucial for conducting thorough and extended testing sessions without the need for frequent breaks to cool down the equipment, thereby enhancing productivity and testing efficiency.
  • Wide Measurement Range: With a range that extends up to 20 milliohms, the MOM200A is versatile enough to handle a wide variety of testing requirements. This range allows for the detection of very low resistance values, crucial for identifying potentially problematic connections that could lead to equipment failure or inefficiencies.
  • Ideal for Poor Connection Detection: The capability to test at lower resistance levels makes the MOM200A particularly effective in finding poor connections. This can help in preventive maintenance schedules, ensuring that all connections are optimal and reducing the likelihood of unexpected downtime due to connection failures.
