Medium voltage cable testing procedure.

Inspection and test procedures 7 3 3 cables medium and high voltage cont optional page 3 ats 2003 8. Any one please explain the hi pot pressure test testing procedure for 3 core 70 sq mm copper mv cable. Damped alternating current voltages are generated by charging the test object to a predetermined voltage level and then discharging its capacitance through a suitable. N medium voltage cable technician certification.

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. If performed by means of direct voltage dc reduce the test set potential to zero and measure residual voltage at discrete. 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. It is commonly used in the industry for acceptance testing prior to energizing the cable and for maintenance testing programs.

Making them useful especially for field testing where transport and space can be issues. We deliver an engaging hands on. Includes testing procedures. Insulation resistance testing is a non destructive test procedure.

Certification cable testing diagnostics medium voltage. Raise the conductor to the specified maximum test voltage and hold for 15 minutes. Periodic off line partial discharge testing at very low frequencies vlf is a diagnostic method for monitoring the insulation degradation of medium voltage cable. Vlf cable testing very low frequency is a technique for testing of medium and high voltage mv and hv cables.

Connect c1 and p1 of the test set to one end of the cable shield. We need to apply 1 414 times 11 1 414 15545 volts dc of voltage between phase to phase or between phase to earth. The high voltage test also called dielectric strength test or hipot test can be made in ac or dc. After more than 50 years avo training remains a global leader in safety and maintenance training for the electrical industry.

Using a four point low resistance ohmmeter connect both c1 and p1 of the test set to one end of the cable shield. The test measures the insu lation resistance between the phases and or between phase and ground. Perform a shield continuity tests on each power cable. If the high voltage test is made in ac it is then this is then more stressful for the sample and made according to the sketch below.

Refer to table 100 6. If the high voltage test is made in dc it is then combined with insulation.
