What is a primary reason for the limited adoption of methods like tan-delta testing?

The primary reason for the limited adoption of methods like tan-delta testing often centers around the high cost of testing equipment. Tan-delta testing, which assesses the insulation condition of electrical apparatus, requires specialized and often expensive testing devices that can provide accurate and reliable results. These costs can be a significant barrier for many organizations, especially smaller ones or those operating under tight budgets.

Additionally, while factors such as insufficient personnel training, lack of regulatory requirements, and complexity of the testing procedure can influence adoption rates, the financial implications of acquiring and maintaining the necessary equipment typically stand out as a more substantial hurdle. This makes high-quality testing less accessible and can lead organizations to opt for more cost-effective diagnostic methods that do not require the investment in advanced technology.
