Megger MTO210 Transformer Winding Ohmmeter

Code: Megger MTO210


 
Datasheet PDF, 0.54 Mb
   

Description

• Direct 2-channel digital reading (1 µO to 2000 O)
• DC test current up to 10 A maximum
• 0.25% measurement accuracy
• Integrated demagnetization feature
• Tests operation of on-load tap-changers
• Very fast auto safety discharge circuit 

 

The MTO210 Transformer Ohmmeter is a line-operated, field-portable instrument designed specifically to measure the dc resistance of all types of magnetic windings safely and accurately. It can test transformers and rotating machine windings and perform low-current resistance measurements on connections, contacts and control circuits. 

The Transformer Ohmmeter is extremely useful when testing the windings and contact resistance of tap-changers with "make-before-break" contacts and voltage regulators. This action will check for pitted or misaligned contacts as the instrument will give an indication if either condition occurs.
