The DMO200 is ideal for measuring busbar joint resistance. Before making connections ensure that the supply is off and necessary earths have been applied.

Connect the high current leads to the busbar, ensuring that the joint resistance to be measured is in the circuit. Connect the sense leads as close as possible to the joint to be measured. Select the desired test current using one of the preset test currents (or use the adjust knob to set a custom test current). Switch the output on, and the current rises to the preset current. Switch the output off again, and the reading is held on the display.

The DMO200 is also suited to all low resistance measurements on power systems, and is particularly suited to measuring contact resistances on substation circuit breakers, isolators and grounding equipment. The unit has a powerful output capable of driving 200A through 20m output leads to reach the contacts of even the largest circuit breakers. Optional output lead extensions are available which extend the high current and sense leads by 3, 5 or 10m.

  • T&R's DMO 200 features pre-settable test currents with 3 programmable buttons to easily set frequently used test currents.
  • The test current ductor can be set to any value between 1 and 200A. The output is smooth dc, and the current is maintained at the pre-set level.
