Megger supplies the MOM600A model of microhmmeters for industrial environments.
Switchgear breakdowns are frequently caused by excessively high contact resistance at breakpoints and busbar joints.
Moreover, overheating risks are becoming more serious due to the fact that today's distribution networks have to carry heavier loads.
Checking contact resistances at regular intervals detects faults before they cause overheating. And here, an ounce of prevention is worth a pound of cure.
Microhmmeters are used to measure contact resistances in high-voltage breakers, disconnecting switches (isolators), knife-contact fuses, bus joints and line joints among others.
The MOM600A microhmmeters are in a class apart on world markets. Designed for use from the Arctic to the tropics, this rugged and compact device is ideal for field work.
A complete set of equipment comprises of a set of highly flexible cables (including separate measurement cables) and a sturdy transport case.
