The purpose of the User Manual provides the information on the proper op-

eration  of  the  transformer oil  breakdown voltage tester  "UIM-90" (hereinafter − 

Oil tester) and is the main source of operating instructions. 

 

The User Manual contains information on the purpose, contents, technical 

specification, design and operating principle of the Oil tester and its units as well 

as its tools, marking, sealing and packaging. 

1 Description and operation 

 

1.1 Purpose of the product 

 

1.1.1 The purpose of the Oil tester is measuring the breakdown voltage of 

transformer  oil  and  other  insulating  liquids  dielectric  in  accordance  with  the 

specified algorithm according to the requirements of IEC 60156:2018 (hereinaf-

ter – IEC) or arbitrary custom settings. 

 

1.1.2 The Oil tester can be additionally equipped with: 

 

– built-in  Bluetooth  adapter

*

,  which  is  used  to  connect  to  a  Personal 

Computer (hereinafter – PC) to remotely control the Oil tester, save and process 

test results; 

 

– built-in thermal printer

**

 

to print the report; 

 

– built-in rechargeable battery

***

 

1.1.3 The Oil tester is portable equipment. 

                                                

*

 

- for models UIM-90 (221/В); UIM-90 (221/ВР)

 

**

 

for models UIM-90 (221/Р); UIM-90 (221/ВР) 

***  - for models UIM-90 (221); UIM-90 (221/В); UIM-90 (221/Р);UIM-90 (221/ВР)
