A range of test voltages for insulation resistance tests up to 5 kV for MIT515/MIT525,10 kV for MIT1025 and 15 kV for MIT1525 are available, including a user selectable voltage range which can be set between 40V or 100 V and 5000 V, 10000 V or 15000 V depending on model.
Reset Default Settings Breakdown vs. Burn mode In breakdown mode insulation tests are automatically stopped when a fault causes the applied voltage to drop rapidly. Burn mode IR tests ignore breakdown and continue to test the insulation and are therefore destructive tests. Burn mode is used to purposely create a carbon track in insulation to facilitate fault location. MIT525, MIT1025 and MIT1525 to ensure that records saved A low resistance alarm sounds when the resistance level of an in the instrument are time/date stamped correctly.

accompanied by an intermittent beeper, (see Voltmeter pg. Breakdown mode / burn mode This is especially likely in electrically noisy environments.
The insulation resistance ‘IR’ test operates in either ‘Breakdown’ or ‘Burn’ mode. Should electrical noise be present it will cause a current to flow Default mode is breakdown. 5 seconds for the duration of a resistance test. It is not PowerDB Pro, Advanced and Lite are possible to log voltages in voltmeter mode. Megger’s asset and data management software packages with integrated If temperature entry has been activated a prompt will appear. PC running PowerDB Pro, PowerDB Advanced or PowerDB Lite via a USB cable.
Check the product CD provided with the instrument for a folder named, “Megger USB.” If this folder exists, use it when starting PowerDB for the first time to find the driver, if not allow the operating system to search the internet for the driver. 15 kV insulation resistance testers (IRTs), and many more. PowerDB Lite is bundled with the Megger’s MIT and S1- Series. The new S1-Series has remote control capability and a specific application to enable remote control testing of assets.
Scroll down the PowerDB form until you see a table with cyan available in the PowerDB form representing three filled headers. RIGHT CLICK once on one of the cyan phases named A, B and C.

On screen error reporting Should an error be detected during the operation of the MIT515, MIT525, MIT1025 or MIT1525 an error code is reported preceded by ‘Err’ with the read handbook warning. Error codes are given in the following table. Timed IR test Measurement Modes A timed test IR(t) will automatically ‘Spot’ IR test terminate an insulation The spot insulation resistance test (IR) is selected on the test test after a preset time.

Up and down arrow buttons are used to change the t1 and PI results 1.5 are regarded as acceptable by IEC60085- t2 default values and OK confirms each setting. 01:1984 for thermal class rating A, and PI results 2.0 for thermal class ratings B, F and H. on the central rotary switch. Timer t1 is set using the up and Step Voltage Test down arrow buttons and OK confirms the setting. The SV test is a controlled overvoltage test that can be applied to stator and rotor windings on synchronous and The ‘DD’. The reference standard for step voltage testing is IEEE 95- 2002.
Ramp voltage test The ramp voltage test is an overvoltage test similar to the SV test but with improved control and warning of potential insulation failure. The slow continuous voltage ramp is less likely to result in unpredictable damage to the insulation than the rapid step increases employed in SV test. Measurement Techniques Understanding Measurement Currents Insulation resistance is defined as the dc test voltage divided In the case of dry insulation, conductance current may be by the total current flowing in an insulator.
The total current negligible and the leakage current may be low, in which case has four components. Alternatively, screened leads are available as an optional accessory from Megger. When using a screened lead the screen is plugged into the Guard terminal, diverting any leakage currents. Game virtual city. This considerably improves measurements made with a floating output, where the leads might touch each other or another object other than the test piece. There are three test terminals marked +, - and GUARD. These must be switched off to clear the message before further terminals are designed to accept only genuine Megger test testing is permitted. The fuse should be replaced by an leads.
