The MOM2 test system is designed to serve a number of applications. The most common are contact resistance measurements of low-, medium- and high-voltage breakers and also at bus-bar joints, and other high current links.
If the contact resistance is too 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.
At 10 kA a contact with the resistance 0.1 mΩ gives a power loss of 10 kW. This power loss in one single point will definitely confer a temperature rise, which may result in overheating and possibly premature failure.
The MOM2 Micro-ohmmeter is a lightweight, handheld unit designed to deliver up to 240 Amps and measure the resistance of circuit breaker contacts, bus-bar joints, and other high-current links. This product is designed with safety, ease of use and versatility in mind.
The MOM2 can be used anywhere to measure a low resistance value with high accuracy. With the MOM2, it is possible to make measurements according to the DualGround™ method. This means that the test object will be grounded on both sides throughout the test giving a safer, faster and easier workflow.
Its ruggedness and light weight make the MOM2 very suitable for field work, such as in substations. The unit comes with a strong rubber holster accessory which makes it extra durable. The MOM2 is capable of testing for a full day without recharge. It can store 190 test values and transfer test data to a PC via Bluetooth.
The Bluetooth feature can also be used in conjunction with the wireless headset to provide an audible pass/fail signal against user-adjustable limits as tests are performed.
