Checking electrical insulation is a must with Insulation resistance tester!
Insulation resistance testers are crucial as low voltage circuit breakers require Insulation testing. Once the electrical insulation is created, it starts aging and begins to fall apart in its performance. Harsh, temperature extremes and chemical contamination conditions, may create additional decay. Moreover, specific environments may cause further worsening, along with power reliability. Through Insulation resistance, tester Insulation tests are performed to assure satisfactory degrees of insulation resistance among stages and from phase to ground. To test the integrity of the insulation, the test equipment is utilized to apply an overvoltage to test. The fundamental reasons for performing insulation resistance testing include: To be used as a quality control measure at the time a piece of electrical equipment is produced
To be used as a troubleshooting tool.
To be used as an installation requirement to help ensure specifications are met
To be used as an occasional preventive maintenance task
Let's talk about one brand that is most commonly used and most preferred choice of masses _ Megger Test Equipment: We will talk about first - good insulation versus poor insulation. The difference lies in the resistance; Good insulation has high, and poor insulation has comparatively low resistance. Wires are protected with resistance sheathing with an end goal to contain the conductivity of either a copper or aluminum wire. Its most important to check the wires as some current leaks out, even if the wire is insulated. An imperfection in the insulation will allow for electricity to escape, which can be damaging to electrical circuits and even machinery. Digital Megger insulation tester is a perfect instrument detrimental in the leakage current giving the complete information to calculate the amount of contamination that is in the insulation. There are various Megger Test Equipment, and each instrument has its specialty though all the equipment is good enough in predicting relevant results, as per the requirement! It's essential to regularly test the insulation, as issues can be identified and fixed before any mishap or equipment failure occurs.
Various factors can decide what tester is right for the job:
