Preventive testing is conducted to identify potential hazards of equipment in operation, prevent accidents or equipment damage, and to inspect, test, or monitor equipment. It also includes testing with oil or gas samples to assist factories in better protecting electrical equipment, ensuring safer and smoother electricity use, avoiding power failures, and avoiding losses. However, there are many testing and prevention methods in preventive testing, insulation test for power cables is one of them;
Insulation resistance testing is one of the numerous quality assurance tests and processes used by our cable experts to check the compliance of our power cables. Our advanced facilities also conduct independent testing for power cables from third parties to ensure that unqualified cables do not enter our broader supply chain.
Insulation resistance testing is a key test for cables, as it can measure the insulation effect of the cable. Poor insulation may cause short circuits, electric shocks, or fires.
The steps for testing insulation resistance are as follows:
Connect the electrode interfaces of the testing instrument to the metal conductors at both ends of the wire and cable to be tested.
Set the parameters of the testing instrument, including measurement range, current, etc., and turn on the power.
After the test command appears, start recording the resistance value.
After recording the test, turn off the power and disconnect the test instrument from the wires and cables to be tested.
