In a perfect world, current that is sent along a conductive wire is supposed to reach the intended destination in full. However, this does not happen in the real world because some of the current is usually lost along the way. There are different reasons why the current gets lost along the way. In an attempt to prevent the loss of current, resistant sheathing is used to insulate conductive wires. Here are facts regarding Insulation tester.
In some cases, current is allowed to escape and get lost due to imperfection in the material used to insulate conductors. When this happens, a lot of harm is done to electrical circuits and machinery. For safety purposes, routine testing can help in determining if the insulation is performing well. Problems can be identified through routine tests before equipment failure or injury happens.
A cladding tester is usually used to carry out the testing. The tester tests the resistance of the insulating material to the flow of current thus, determining its integrity. There is very little loss of current for insulating materials of high quality. On the other hand, insulating materials of poor quality will allow large amounts of current to escape.
Testers measure various kinds of current when they are used to measure the quality of cladding a material is made of. The three main kinds of currents measured are capacitive, absorption, and leakage currents. Capacitive current refers to the initial burst of current that happens when voltage gets first applied to conductors.
Capacitive current can be equated to the volume of water that comes out of a pipe immediately a tap is opened. Once the tap is opened, water usually flows out at a higher rate but as the pipe gets filled with water completely, the rate drops rapidly. For the case of a conductive material, the amount of current flow drops once the conductor becomes fully charged.
Just like capacitive current, absorption current initially flows in large amount before dropping. However, the rate at which absorption current drops is much lower compared to that of capacitive current. Potential energy is stored in the cladding making the flow of absorption current to drop gradually. When testing the cladding of a material using time resistance method, absorption current is a very important aspect.
Conduction current is the other name used for leakage current. This current is present through and over the cladding and it is small and steady in nature. The increase in leakage current implies deterioration of the cladding over time as well. In insulation test meter, the rise in leakage current is indicated as a reduction in resistance.
There is a wide range of cladding testers in the market today. The various models of these products are made by manufacturers located in various countries. The quality of individual testers depends on the manufacturer of the equipment. Also, the various models of these devices in the market are used in different applications. There are testers that are meant for residential testing and those that are meant to be used in industries.
