The Megger MOM3 handheld 300 A micro-ohmmeter is purpose-built for measuring the resistance of critical electrical components such as circuit breaker contacts, busbar joints, and other high-current links. Its effectiveness in conducting these measurements is achieved using an ultracapacitor, a technology that distinguishes it from conventional capacitors. The size and great interface of the product makes it very practical in use for daily work on site.
The MOM3 micro-ohmmeter includes:
- Ultra Capacitor Technology: The MOM3 employs an ultracapacitor that can store a significant amount of energy compared to standard capacitors. This capability allows it to generate a very high output current during discharge, a crucial requirement for accurately measuring low resistances in high-current components.
- Low Internal Resistance: The ultra capacitor's low internal resistance ensures that the energy it stores is efficiently and effectively discharged, contributing to the micro-ohmmeter's high accuracy when measuring resistance.
Versatile Use: The MOM3 micro-ohmmeter is designed to be highly versatile, making it suitable for use in various settings. It can be employed anywhere to measure low resistance values with a high degree of accuracy, ensuring reliable results.
The MOM3-CP BK-30491 includes the MOM3 with kelvin clamps, 3m cable set and kelvin probes.
Product Features
The MOM3 test system is designed to serve several applications. The most common tests are contact resistance measurements and connection checks for low, medium, and high voltage circuit breakers, as well as for busbar joints and connections. MOM3 is also ideal for all applications in which a low resistance need to be verified, e.g. in switches, disconnecting devices, safety ground connections, welding points, fuses and cables.
If the measured resistance is abnormally high this will lead to power loss and temperature rise, which often leads to serious trouble. To avoid such problems, it is necessary to check the resistance at regular intervals.
