What Is High Voltage Cable Testing?
Cable diagnostic tests are predictive to evaluate a cable’s relative degree of deterioration against the newly created state. The chances are that the cable will work correctly sometime during the lifespan of the cables. Asset managers are expected to determine the ageing and overall state of service-aged cable networks, such as assessing what needs to be replaced or updating on the network with high voltage testing equipment.
Why Is Cable Testing Needed?
A cable defect can be seen several times before it becomes a real problem. A visual inspection of all of your cables is an ideal way to find trouble before you have downtime. Experts check for copper corrosion, insulation cracks, cable moisture, and various other cable damage indicators.
There is a large demand for cable inspection techniques to ensure cable defects are in good condition and cable errors are found rapidly. Cable defects cost money and cause a disturbance.
Cable checks to predict and deal with defects are of critical importance for all those involved in electricity distribution. A wide variety of testing techniques and high voltage cable testing equipment are available to effectively solve this issue, but cable testing can nevertheless be a difficult task.
Therefore, a resource as important as the high voltage cable testing equipment is access to expertise which helps to choose the best equipment for the job and to use it to achieve the best results.
Types of Cable Tests
Field diagnostic tests may be carried out on cable systems during different stages of its service. Cable testing is specified in accordance with the IEEE 400 standard as:
Installation Test
It is carried out after installation of the cable, but before installation of any joints and terminations. The purpose of these tests is to detect any damage to the cable’s output, transport, and installation.
Acceptance Test
This is usually conducted after all cables and adapters have been installed, but before the cable is energized with system voltage. It is intended for the detection of cable accessory shipping and installation damage.
Maintenance Test
This is done during the cable system’s service life. The aim is to evaluate the condition and to track cable system serviceability to initiate appropriate maintenance procedures.
Methods of Cable Testing
The approach to be used depends heavily on the age and form of an installed cable system. Many methods can be carried out in accordance with such conditions as the voltage used or the length of the test as an acceptance or maintenance test
Cabling is a costly company and must be carefully handled. Once all roads are concealed, the costs of substitution are greater.
The fault does not always appear to crush, bend, or twist. Make sure your high voltage testing equipment used when installing are safe from the actions of other employees. This is much cheaper than modifying future cabling. If cable routes are guarded without any way of opening them between the termination and installation, cables may be checked until the routes are secured.
