Insulation resistance quality of an electrical system degrades with time, environment condition i.e. temperature, humidity, moisture and dust particles. It also get impacted negatively due to the presence of electrical and mechanical stress, so it’s become very necessary to check the IR (Insulation resistance) of equipment at … See more We can test your circuits for the existing connections and melted fault areas that may have occurred during a fire event. These results are then analysed and specific circuits can be isolated and replaced to insure … See more A multimeter is used as an insulation tester in some conditions and mostly a continuity test only is performed. But for detecting and testing for a leakage current during a normal or overloaded condition, a special instrument … See more This can be separated into mainly two categories: 1. Electronic Type (Battery Operated) 2. Manual Type (Hand Operated) See more WebTest & Measurement Instruments with Engineering Support Instrumart
