In the context of cable testing, what is the main reason for the limited adoption of methods such as tan-delta testing?

The limited adoption of methods such as tan-delta testing primarily relates to the high cost of testing equipment. Tan-delta testing requires specialized instruments that can accurately measure the dielectric properties of insulation systems. The investment in such equipment can be significant, making it less accessible for some organizations or utilities, particularly those with budget constraints or smaller operations.

Organizations often prioritize testing methods that provide a good balance of cost-effectiveness and reliable results. Consequently, the high capital expense associated with tan-delta testing can deter entities from implementing this method, favoring lower-cost alternatives despite the potential benefits offered by tan-delta testing in terms of assessing insulation condition and reliability.

While issues like equipment availability, personnel training, and result interpretation can influence the use of certain testing methods, the upfront cost associated with tan-delta testing remains a predominant factor hindering its widespread application in the field.
