DESCRIPTION
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.
Micro-ohmmeters are used to measure contact resistances in highvoltage
breakers, disconnecting switches (isolators), knife-contact
fuses, bus joints, line joints etc.
The MOM600A? is in a class apart on world markets. Designed for
use from the arctic to the tropics, this rugged, compact micro-ohmmeter
is ideal for field work.
A complete set of equipment includes a set of highly flexible cables
(including separate measurement cables) and a sturdy transport
case

APPLICATION EXAMPLES A. Measuring the resistance of a circuit breaker element 1. Connect the micro-ohmmeter to the circuit breaker. 2. Set the current (100 A in this example). 3. Press the resistance pushbutton. 4. Read the result. B. Measuring the resistance of busbar joints 1. Connect the micro-ohmmeter’s current cables to the object being tested. Do not connect the sensing cables since measurements will be taken using an external movable voltmeter. 2. Set the current (100 A in this example). 3. Connect an external voltmeter to the bus. 4. Read the voltmeter (0.1 mV = 1 μΩ in this example). 5. Move the voltmeter to the next joint. 6. Repeat step 4.
