Cable insulation resistance test standard iec.

Z 2 electrical insulation testing. Insulation resistance testing guide. Table 100 22 minimum radii for power cable. With a little record keeping and common sense however you can get a good picture of the insulation condition from values that are only relative.

Ieee400 1 2007 ieee guide for field testing of laminated dielectric shielded power cable systems. Maintenance insulation resistance testing can be performed on a regular basis and the collected data used to indicate if the conductor insulation is deteriorating over time. S iec 60840 edition 4 0 2011 11 iec standards power cables with extruded insulation and their accessories for rated voltages above 30 kv um 36 kv up to 150 kv um 170 kv test methods and requirements câbles d énergie à isolation extrudée et leurs accessoires pour des tensions. Deviations from the baseline information permit evaluation of the insulation.

Test results are dependent on the temperature of the insulating material and the humidity of the surrounding environment at the time of the test. If during periodical testing insulation resistance of cable is found between 5 and 1 mω km at buried temperature the subject cable should be programmed for replacement. If insulation resistance of the cable is found between 1000 and 100 kω km at buried temperature the subject cable should be replaced urgently within a year. Insulation resistance decreases in temperature or moisture.

The resistance is determined by the glow wire test. This type of test is a form of preventative maintenance. Cables for rated voltages of 1 kv um 1 2 kv and 3 kv um 3 6 kv reference number iec 60502 1 2004 e international standard iec 60502 1 second edition 2004 04. The equipment under test is brought into contact with the hot filament for 30 seconds.

The temperature amounts to. Historically many field electricians use the somewhat arbitrary standard of 1 megohm per kv. If the insulation resistance falls below an accepted user dictated value or falling rapidly over time then cable. Power cables with extruded insulation and their accessories for rated voltages from 1 kv um 1 2 kv up to 30 kv um 36 kv part 1.

The international electrical testing association neta specification maintenance testing specifications for electrical power distribution equipment and. The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. Insulation resistance test data may be used to establish a trending pattern.
