Commercial testing of installations mandates the use of insulation resistant tester to identify efficiencies as well as deficiencies in the electrical system. The certification agency observes these practices before certifying that installation is per regulations. When such best practices are followed the risk of short circuits and potential fire hazards is completely negated. More often than not, both the contractor and the certifying agency falling short in these practices lead to accidents and avoidable disasters.Insulation testing by a properly designed tester should exhibit sharp voltage rise and retain that voltage through several higher resistances.
Megger is a renowned name in test and measurement equipment manufacturing with research and manufacturing facilities in United States of America, Britain, Germany and Sweden. Megger equipment's are used in telecommunications, electric power and building wiring industries. Megger has recently announced the introduction of enhanced Megger insulation testers and continuity testers. They are CAT IV compliant and rated to 600 volts operation. The main feature of this tester is the variable voltage from 10 V to 1000 V with incremented steps that allow tight control of test voltages.
The Megger insulation tester is ideally suited for use in motor testing, cable testing and major electrical installations. Other applications include avionics, automotive and building maintenance. User safety is the highest rating accorded for this device due to its use in high voltage environments. For safety, the device features live circuit detection as well as protection. Some of the Megger models are equipped with Bluetooth data transfer capability as well as data storage memory.
