Introducing the new version of the popular MIT1020 by Megger. With the MIT1020/2, the operation of the instruments remains unchanged, but overall improvements have been made.
The new 10 kV insulation resistance testers from Megger is designed specifically to assist you with the testing and maintenance of high voltage electrical equipment. IEEE 43-2000 recommends the use of 10 kV for motor windings rated above 12 kV and the Megger MIT1020 facilitates this.
The case is incredibly rugged and easy to carry, being made of tough polypropylene and achieving an ingress protection rating of IP54. In addition, the model number is marked on both the top and side of the case for ease of identification in stores or vehicles.
The instruments have a large easy to read backlit LCD display making it equally suitable for use in both bright sunlight and poorly lit environments.
Information displayed includes resistance, voltage, leakage current, capacitance, battery status and time constant. In addition, the elapsed time of the test is displayed constantly removing the need for separate timers.
The instrument can test when being powered by the mains or its internal rechargeable battery, a great benefit when site conditions are unknown or long term testing is required.
The controls of the instrument are clear and unambiguous and a “quick start” guide is included in the lid of the instrument removing the need to carry bulky manuals under site conditions. The instrument is fitted with a guard terminal to enhance accuracy. The guard test lead is included as standard with the instrument.
To further enhance the flexibility of the instruments both have the facility to set the test voltage in steps from 50 V to the maximum output voltage avoiding the expense of several insulation resistance testers to meet your application needs.
These insulation test instruments are designed to meet the highest safety standards and meets the requirements of EN61010. In addition, the instruments measure the voltage at the terminals and if this is above 50 V then the instruments will display the high voltage warning and inhibit testing. At the end of the test the instruments will automatically discharge the energy transferred to the equipment during the test phase.
The MIT520 and MIT1020 are equally suited to routine testing and diagnostic regimes being pre-programmed with IR, PI, DAR, SV and DD profiles.
