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, imperfections in cladding material allow current to leak and get lost to the surrounding. The leaking current can cause a lot of problems to the machinery and electrical circuits. That is why in order to maintain safety, the cladding needs to be tested on a regular basis. Doing this helps to identify problems before they cause equipment failure or harm people who handle the equipment through electrocution.
This testing process is done using a pieces of equipment referred to as an cladding tester. The equipment tests the integrity of the cladding by measuring its resistance to the flow of current across it. If the cladding is of high quality, it means that very little current will escape through it. On the contrary, if the cladding offers very little resistance, then a higher amount of current will flow across it.
When measuring the quality of material used to make the sheath, different kinds of current are tested. Absorption, leakage and capacitive currents are the three main types of current tested. The current that occurs immediately when voltage is applied to conductors is referred to as capacitive current.
Capacitive current is the same as the first burst of water that flows out of a hose when the tap is first opened. The flow of water is usually very high initially, but it rapidly drops as the hose becomes fully filled with water. In this case, it is the conductor becoming fully charged that leads to the drop in the current flow.
Absorption current is similar to capacitive current in that it starts out high but then drops. The only difference between these two kinds of currents is that absorption current drops at a much lower rate compared to capacitive current. The gradual drop in absorption current is due to the storage of potential energy in the cladding. Absorption current makes an important part of the time resistance method of cladding testing.
The third type of current tested is leakage current, which is also called conduction current. Unlike the other currents which drop over time, this type of current is small and steady. The current occurs both over and through the insulating sheath. Sheath that deteriorates in quality over time causes the leakage current to increase as time passes. The increase in leakage current as resistance decreases is indicated by an insulation test meter.
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.
