Full current is expected to reach the desired destination when sent along a conductive wire under perfect conditions. However, some current is usually lost during the transmission, making this to be impossible in the real world. Several factors make some current to be lost during the transmission. However, this loss of current can be managed by insulating conductive wires using resistant sheath. This is what Insulation tester is all about.
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 the piece of equipment that is used to accomplish the testing. The equipment works by measuring the resistance of the cladding to flow of current. This indicates the integrity of the cladding in turn. Cladding that is of high quality allows very little current to escape through it. However, low-quality cladding allow huge amounts of current to escape through.
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 similar to the first burst of water from a hose. The initial burst is usually very high, but it then reduces very fast. The drop is caused by the fact that the hose becomes filled with water after a sort while and the flow of water becomes steady. In the case of electricity, the conductor becomes fully charged, hence the drop in 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.
Leakage current is also referred to as conduction current. This is a small, steady current that is present both over and through the cladding. If the leakage current increases over time, it implies that the cladding is deteriorating over time too. Insulation test meter usually indicates these increase in leakage current as decrease in resistance.
The market today is filled with a wide variety of cladding testers. Manufacturers are located in various countries worldwide. Different manufacturers make products that have different levels of quality. Similarly, the applications that different products are used for vary. One should be careful with their choice because there are residential, commercial, and industrial testers in existence.
