16.1  Cleaning the oil breakdown voltage tester 

 

 

  DANGER   

Electrical voltage on device

 

Danger to life or risk of injury from electrical voltage. 

  Switch off the device before cleaning. 

  To disconnect the device completely from the mains voltage, pull 

out the mains plug. 

 

 

  WARNING 

Fire hazard posed by petroleum ether or other cleaning solvent

 

We recommend using cleaning solvent to clean the test chamber of the 
oil breakdown voltage tester and the test vessel. The cleaning solvent 
is highly flammable and in some circumstances may cause a fire.   

  Do not smoke when working with cleaning solvent.   

  Avoid naked flames.   

           

NOTICE   

Damage to the device may be caused by using the wrong cleaning agents

 

  Do not use any abrasive, corrosive cleaning agents or strong solvents. 

  Ensure material compatibility. 

  Do not clean the product with acetone or thinner. 

  Never clean electrical devices with water. 

     

Prerequisites 

 

 

Safety gloves to prevent coming into contact with insulating oil   

 

 

Mild detergent for cleaning the surfaces of the device 

 

Petroleum ether or other similar mild solvent for cleaning the test chamber 

 

Lint-free cleaning cloth
