Micro-ohm measurement and contact timing

Low-resistance test procedures, such as contact resistance measurements for disconnectors, earthing switches and busbar connections, are performed regularly to identify poorly maintained and damaged contacts.

The integrated micro-ohmmeter in CIBANO 500 allows you to measure contact resistance. In addition, it allows you to perform timing tests of the main contacts in relation to the auxiliary contacts in disconnectors and earthing switches. The motor can be powered by CIBANO 500 during testing to ensure complete safety.
