After installation, the cable must undergo a series of tests to verify its condition before it is energized.

• Continuity and Resistance Test: This confirms that the conductors are not open-circuited and measures the resistance of the conductors.

• Insulation Resistance Test (Megger Test): This test measures the insulation resistance between conductors and between conductors and earth to check for any insulation damage.

• High-Voltage (Hi-Pot) Test: A DC or VLF (Very Low Frequency) test is performed to check the cable's dielectric strength and to detect any potential weaknesses in the insulation or jointing.
