8 -8- TIC ELECTRICAL TYPE TESTS 3.1 General Tests at elevated conductor temperature For the tests with the cable at elevated temperature, a reference loop for temperature control of the conductor was installed. The reference cable was cut from the total cable length submitted by the client intended for the type test. This reference loop was installed close to the main loop in order to create the same environmental conditions as for the test loop. The heating currents in both the reference loop and the test loop were kept equal at all times, thus the conductor temperature of the reference loop is representative for the conductor temperature of the test loop. All three phases of both the reference loop and the test loop carried the same level three-phase current. Annex A, method 1 of IEC was used as a guide.
