Megger MIT1525/2-US ADVANCED 15kV IRT (Insulation Resistance Tester) 2024 PIP (1016-101)

Details

The Megger MIT15252 (1016-101) Advanced Digital Insulation Resistance Tester and Megohmmeter offers rugged dependability, a long service life, and accurate measurements. The "no compromise" approach offers further levels of safety than simply complying with the relevant safety standards while the intuitive color custom display allows for users to work in extreme environments with an unbeatable viewing angle.

The MIT1525/2 provides an excellent level of noise immunity, test performance, and safety and offers a maximum test voltage up to 15 kilovolts. This Advanced range model allows users to record test results, transfer results to the software or mobile app, and perform diagnostic insulation testing. Users are provided with additional noise immunity for power distribution environments and the ability to either increase or decrease the output current.

The MIT1525/2 offers rapid charge batteries and operation from an AC source when the battery is flat or empty. An intuitive user interface ensures that no time is lost remembering how to use the tester. Simplicity of operation is achieved with two rotary switches and a large backlight display which enables various measurement information to be displayed simultaneously. A graphical quick-start guide is provided inside the lid to assist first-time users.

Measurement accuracy is of high importance for any insulation resistance measurement and is particularly important to ensure that the accuracy is maintained up to higher IR values that are required by some applications. This Advanced range model provides an excellent ±5% accuracy all the way up to 1 TΩ at 5000V, 2 TΩ at 10000V, or 3 TΩ at 15000V. Users should always check that the expected range of measurements sits within the accuracy range capability of the instrument.

The Polarization Index test can be time consuming, with a ten minute test (30 minutes on 3-phase) and with multiple items to test, any time saved is a bonus. The PIp function helps users save that valuable time. The PI predictor function uses the first part of the IR curve to predict the rest at five minutes into the test. The PIp can start as early as three minutes into the test and will stop when it is confident in the prediction.

The RE>ACT test mode feature will revolutionize the reliability of measurements. When insulation testing, it is essential that any re-absorption current from the insulation under test is fully discharged before starting the test. Remaining absorption current, depending on polarity, can result in IR measurements that are falsely high or low, with the potential to incorrectly pass any failing insulation. The RE>Act mode not only measures this reabsorption current but also provides an indication to the user of the impact it will have on the instrument's measurement range and accuracy.

Safety of operation is built in with this 15 kV model safety rated to CAT IV 1000V up to an altitude of 4000 meters.

The dual case design features a tough outer case to protect the tester from knocks and drops along with a fire retardant inner case. The case IP rating prevents moisture and dust ingress when storing or carrying the instrument. The lids have velcro-on pouches ensuring that leads remain with the instrument at all times. Case lids are removable for improved access to the terminals.

A multitude of voltage warnings help ensure user safety with five levels of warnings. Before testing has started, the instrument will provide these warnings:

Level 1 : Live voltage above 30V has been applied.

Level 2 : 75% of the instrument's noise limit has been exceeded, users should check filter settings.

Level 3 : 100% of the instrument's noise limit has been exceeded, warnings and tests are inhibited.

Level 4 : The external voltage overheating discharge resistors disconnect.

Level 5 : The fifth warning is a unique one. During testing in high noise environments, induced noise surges can result in extremely high voltages being applied to the instrument. In the event that these voltages are higher than the instrument's reinforced insulation limits, the instrument will halt the test to reduce terminal voltage and warn the user not to touch the instrument.

Two important safety features are added with the RE>Act test mode. Firstly, it removes the possibility to pass insulation that should have been failed, and secondly, it can also be used to monitor discharge following a test. This means that the user can ensure that a dangerous return voltage will not occur.

Supplied test leads are double insulated with clamps rated at 3 kV, equivalent to 6 kV single insulation for the medium clip lead set and 5 kV equivalent to 10 kV single insulation for the large clip. The 15 kV lead set is insulated to 15 kV.

All test leads feature non-detachable test clips and the four millimeter high voltage insulated plugs lock into the instrument for additional safety.

Five preset voltage ranges are provided in insulation test mode along with a user-settable lock voltage range. The preconfigured diagnostic tests include Polarization Index (PI), Dielectric Absorption Ratio (DAR), Dielectric Discharge (DD), Polarization Depolarization Current (PDC), Stepped Voltage (SV), and Ramp Test.

This Advanced range model also features memory storage with time/date stamping of results, logging of data, and recall of results to the screen. A fully isolated USB interface can be used for safe transfer of data to software. Users can utilize the mobile app, browser-based software of CertSuite Asset for testing and reporting. Users can optionally utilize the PC based asset management software, PowerDB Pro (not included).

CertSuite Asset is a cloud-based industrial asset testing management software. With the CertSuite Asset app, users can transfer results from the insulation resistance tester while testing straight onto an Android or iOS mobile device or Windows laptop via USB cable.

CertSuite Asset Lite comes standard with the MIT1525/2. Test results can be tagged with Asset ID and transferred to the CertSuite Asset Lite software directly from the tester, removing the need for writing down results.

The full CertSuite Asset app (not included) allows for test results to be tagged with Asset data and transferred to the CertSuite Asset software along with the ability to store results, comments, and photos. The full package connects to multiple users for remote reviewing by other team members while on site from different locations or for the head office to access results with relevant permissions.
