Precautions of Transformer Oil Test Equipment

1.The selection, placing and electrode distance of the oil sample before testing shall meet relevant national and industrial standards.

2.The operators or other personnel are strictly forbidden to touch the casing after the power is switched on to avoid accidents.

3.The power shall be cut off immediately if any abnormal event is found during the operation.

4.New oil cup or cleaning the oil cup should be 24 times breakdown after test execution. The oil cup should be soaked with clean oil when not being tested.

Types of trasnsformer Oil Tester

Types of Transformer Oil Test Equipment

Oil Breakdown Voltage Tester:

Purpose: To measure the insulation strength (breakdown voltage) of transformer oil.
Standard: IEC 60156、ASTM D877/D1816。

Oil Tan Delta Tester:

Purpose: To detect the influence of polar pollutants (moisture, oxidation products) in oil on dielectric properties.
Standard: IEC 60247、ASTM D924

Flash Point Tester:

Purpose: To detect the flash point (flammability) of oil and evaluate its safety.
Standard: ASTM D92 (Cleveland Open Cup Method).

Oil Trace Moiture Tester:

Purpose: To detect the moisture content (ppm level) in oil and prevent a decrease in insulation performance.
Standards: Karl Fischer titration method (IEC 60814), capacitance/resistance method.

Kinematic Viscometer:

Purpose: To measure the kinematic viscosity of oil and ensure its cooling and lubrication performance.
Standard: ASTM D445、ISO 3104

Oil Acid Tester:

Purpose: To measure the acid value of oil (milligrams of KOH required to neutralize 1g of oil) and evaluate the degree of oxidation.
Standard: ASTM D974、IEC 62021

Oil Dissolved Gas Analyzer:

Purpose: To detect dissolved fault gases in oil (such as H ₂, CH ₄, C ₂ H ₂) and diagnose internal faults in transformers.
Standard: IEC 60567、ASTM D3612

Pour Point Tester:

Purpose: Used to measure the pour point of a liquid, which is the lowest temperature at which the liquid begins to flow under specific conditions. This is crucial for evaluating the low-temperature fluidity of liquids and selecting appropriate transportation and storage conditions.
Standard: ISO 3016、ASTM D97

FAQ

01.What are the main types of dielectric strength testers for insulating oil? What are their output voltages?

There are mainly three models: HZJQ-X1, HZJQ-1, and HZJQ-1B. The output voltage of HZJQ-X1 is 0~80KV, the output voltage of HZJQ-1 is 0~100KV, and the output voltage of HZJQ-1B is 0~100KV.

02.What are the advantages of Huazheng's insulation oil dielectric strength tester?

① Power off hold, capable of storing 100 experimental results; ② Capable of measuring and displaying environmental temperature and humidity, as well as displaying the system clock; ③ Equipped with overvoltage, overcurrent, and limit protection to ensure the safety of operators; ④ After the experiment is completed, the thermal printer can be set to automatically print results with the function of switching between Chinese and English.

03.Can you briefly describe the purpose of the dielectric strength tester for insulating oil?

Used to test the breakdown voltage of insulating oil and assess its voltage resistance, it is commonly used in power systems, railway systems, large petrochemical plants, and enterprises.

04.What are the types of electrodes for the dielectric strength tester of insulating oil? What type of electrode do we strongly default to?

There are three types of electrodes for the dielectric strength tester of insulating oil: mushroom head, round head (spherical head), and flat head. Our default dielectric strength is mushroom head (standard electrode).
