Types of Equipment that Need Low Resistance Testing Industries that consume vast amounts of electrical power must include low resistance ohmmeter measurements in their maintenance operations with a unit like a Megger DLRO10HD 10 Amp Digital Low Resistance Ohmmeter . Not only does abnormally high resistance cause unwanted heating, possibly leading to danger, but it also…
Why Measure Low Resistance?
Megger DLRO10HD 10 Amp Digital Low Resistance Ohmmeter Measuring low resistance helps identify resistance elements that have increased above acceptable values. The operation of electrical equipment depends on the controlled flow of current within the design parameters of the given piece of equipment. In the modern age of electronics, increased demands are placed on all aspects of electrical circuitry. MEGGER DLRO10HD Low resistance measurements, with a unit like a…
How Insulation Resistance is Measured
Resistance Readings Considered Relative You have seen that good insulation has high resistance; poor insulation, relatively low resistance. The actual resistance value s can be higher or lower, depending upon such factors as the temperature or moisture content of the insulation (resistance decreases in temperature or moisture). With a little record-keeping and common sense, however, you can get a good picture of the insulation condition from values that…
What Makes Electrical Insulation Go Bad, or Cause Insulation Degradation?
Insulation Degradation Can Be Fast or Slow When your plant electrical system and equipment are new, the electrical insulation should be in top notch shape. Furthermore, manufacturers of wire, cable, motors, and so on have continually improved their insulations for services in industry. Nevertheless, even today, insulation is subject to many effects which can cause it to fail –…
