That is with the same test connections and with the same test voltage applied for the same length of time.

Medium voltage cable testing procedure pdf. Various cable testing practices are covered in the following documentation. It is important to recognize that many factors must be considered to properly characterize the test results obtained from any cable testing program. The cable as well as the type of cable being tested. The test measures the insu lation resistance between the phases and or between phase and ground.

Low voltage or medium voltage shielded or non shielded etc. N medium voltage cable technician certification. After more than 50 years avo training remains a global leader in safety and maintenance training for the electrical industry. In the absence of manufacturer s published data use table 100 1.

Damped alternating current voltages are generated by charging the test object to a predetermined voltage level and then discharging its capacitance through a suitable. It is commonly used in the industry for acceptance testing prior to energizing the cable and for maintenance testing programs. In accordance with icea iec ieee and other power cable consensus standards testing. Pump motor or a short control cable may be vital to a process in your plant.

Making them useful especially for field testing where transport and space can be issues. Vlf cable testing very low frequency is a technique for testing of medium and high voltage mv and hv cables. Experience is the best teacher in setting up the scheduled periods for your equipment. Raise the conductor to the specified maximum test voltage and hold for 15 minutes.

Dac voltage testing is one of the alternative methods of ac voltage testing and is applicable for a broad range of medium voltage high voltage and extra high voltage cables. We need to apply 1 414 times 11 1 414 15545 volts dc of voltage between phase to phase or between phase to earth. An arbitrary test voltage level could result in a cable failure in a circuit that would otherwise have provided long trouble free service at normal operating ac voltage. Periodic off line partial discharge testing at very low frequencies vlf is a diagnostic method for monitoring the insulation degradation of medium voltage cable.

Perform a shield continuity test on each power cable. Refer to table 100 6. Insulation resistance testing is a non destructive test procedure. You should make these periodic tests in the same way each time.

If performed by means of direct voltage dc reduce the test set potential to zero and measure residual voltage at discrete. We deliver an engaging hands on. Includes testing procedures. Inspection and test procedures 7 3 3 cables medium and high voltage cont optional page 3 ats 2003 8.

Vlf systems are advantageous in that they can be manufactured to be small and lightweight.
