Solving the problem of high conductor resistance: the impact of measuring fixtures and solutions



In fields such as power systems and electronic equipment, the resistance value of conductors is an important parameter, which directly affects the performance and safety of the equipment. However, during the actual measurement process, we may encounter the problem that the conductor resistance value is too large. This problem can be caused by a number of factors, one of which is a problem with the measuring fixture. This article will discuss in detail the impact of the measurement fixture on conductor resistance measurement and propose corresponding solutions.

 

First, we need to understand the role of the measurement fixture in resistance measurement. The measuring fixture is a device used to fix the conductor under test and connect it to the measuring instrument. If the measuring fixture is improperly designed or used, it may result in poor contact between the conductor under test and the measuring instrument, thus affecting the accuracy of the measurement results.

So, how to judge whether the measurement fixture causes the conductor resistance value to be too high? Here are some possible clues:

  1. After replacing other measuring fixtures or measuring instruments, the resistance value of the conductor is still too high.
  2. When the position or direction of the conductor under test is changed, the resistance value changes significantly.
  3. When checking the contact surface of the measuring fixture, it was found that the resistance values were different due to different contact forces.

 

If the above clues point to the measurement fixture, then we need to improve the measurement fixture. Here are some possible solutions:

  1. Clean and repair the measuring fixture: Regularly cleaning the contact surface of the measuring fixture to remove dirt and oxides can effectively improve the contact quality. Severely worn measuring fixtures may need to be repaired or replaced.
  2. Optimize the design of the measuring fixture: According to the characteristics and needs of the conductor under test, optimizing the design of the measuring fixture can improve the stability and reliability of the contact. For example, special materials are used to improve electrical conductivity.
  3. Improve the skills and knowledge of operators: Correct operation and maintenance of measuring fixtures can effectively prevent excessive resistance values caused by improper operation. Therefore, regular training and assessment of operators is very necessary.

 

In general, the measurement fixture is an important factor affecting the measurement of conductor resistance. Through regular inspection and maintenance, as well as reasonable design and operation, we can effectively solve the problem of large conductor resistance values, thereby improving the accuracy and reliability of measurements.

The Stranded Conductor Multiplier Resistance Fixtureindependently developed by our company can perfectly solve this problem. The fixture has a clamping force of up to 4 tons. The good structural design avoids the problem that the actual resistance value measured is not in line with reality due to clamp problems. , the conductor multiplier resistance fixture has been loved by the majority of users, effectively solved the actual problems encountered by cable manufacturing companies, and injected new impetus into the production and development of the company.
