Testing 3.3kV cables

[NHG]

We will receive within one month a 3ph 3.3kV cable for supplying power to a motor from a 33/3.3 kV transformer. The cable was in our store for like one year or more. What are the basic testing methods to be carried out on the cable to ensure its healthy condition before placing it in the system. Can you recommend any site that contains information/articles regarding this matter.

Normally IR value is being taken before putting the cable into service. IR value should be more than (2*kV+1). To be more safe, you can go for tan delta test of the cable also.

Suggestion: It may be a good idea to contact the cable manufacturer since the test is somewhat dependent on the cable construction and insulation materials.
