Both Sides Grounded
Within electrical power utilities, switchgear owners and service companies, there is an increased emphasis on efficiency of operations, maintenance and service levels. There is an increased emphasis on health, safety, and environmental compliance. Experience has also shown demands for shorter time periods for testing, while the switchgear is less and less available to be taken out of service.
Many utilities require safety grounds to remain in place during station outages, therefore, the MOM2 was designed with this field safety constraint in mind. DualGround means that the test object will be grounded on both sides throughout the test giving a safer, faster and easier workflow. Minimum time shall be spent in the substation and focus shall be on the test rather than the equipment.

The Kelvin probes (included in BD-59090) are used for a 4-wire Kelvin test. This is a way of measuring continuity resistances ensuring all contact and lead resistances are compensated for, allowing a much greater accuracy in measurements. Each Kelvin probe assembly has two probe tips: one tip is for the current generated; the other will measure the very small voltage present.
The Kelvin clamps (included in BD-59092) use the same principle.




Equipment and methods that supports DualGround™ testing are associated with the DualGround symbol. This symbol certifies the use of groundbreaking technology and methods that enables a safe, fast and easy work?ow with both sides grounded throughout the test.∏∏
