Product Description

Transformer High Voltage Oil Immersed AC DC Hipot Tester

Product Description

A withstand voltage tester is an instrument used to test the insulation strength of electrical equipment, whether the equipment can maintain insulation under high voltage without electric shock or leakage. The withstand voltage tester usually uses DC or AC high voltage signals for testing, and can test the insulation strength of various electrical equipment (such as cables, transformers, switches, sockets, etc.).

AC withstand voltage test equipment, commonly known as AC DC transformer withstand voltage tester, is characterized by small size, light weight and sturdy structure. It is equipped with a full range of functions, has strong versatility, and is very convenient for users to use.

Model Selection

  Different Types of High Voltage Test Transformers
  

   

  Oil-immersed transformer

  Dry-type transformer

  Gas-filled transformer

   

  1. Oil-immersed transformer:
  
  * This type of transformer uses insulating oil as the main insulating and cooling medium.
  * Oil-immersed transformers are usually used in higher voltage levels and larger capacities.
  * Oil-immersed transformers are relatively simple to maintain and low cost, but oil aging and possible leakage problems need to be considered.
  
  2. Dry-type transformer:
  
  * Dry-type transformers use dry insulation materials such as epoxy resin, cellulose material or vacuum pressure impregnation (VPI) treated insulation paper as the insulating medium.
  * Suitable for occasions where space is limited or good fire resistance is required.
  * The maintenance cost of dry-type transformers may be higher than that of oil-type transformers, but they have advantages in safety and reliability.
  
  3. Gas-filled transformer:
  
  * Gas-filled transformers use gas (usually nitrogen or sulfur hexafluoride (SF6)) as the insulating and/or cooling medium.
  * SF6 gas has excellent insulation properties and thermal conductivity and is commonly used in high-voltage and extra-high-voltage transformers.
  * Gas-filled transformers can be designed as fully enclosed switchgear (GIS), suitable for urban environments and underground facilities.

  Features

  1. The use of a new type of time relay allows for a wider timing range (1second to 99 hours).
  2. The adoption of a new type of current relay ensures more accurate and reliable timing, safeguarding personal and equipment safety.
  3. The power frequency test transformer is equipped with new insulation that is moisture-proof, impact-resistant, and has a high insulation grade.
  4. The structure is rationally designed, compact in size, and lightweight.
