The Megger MIT525 is a 5 kV insulation resistance tester designed for diagnostic testing and maintenance of high-voltage electrical equipment. It is suitable for applications involving cables, transformers, motors/generators, circuit breakers, and bushings.
Key Features:
-
Test Voltage Range: 250 V to 5000 V, with user-defined settings in 10 V steps from 40 V to 1 kV and 25 V steps from 1 kV to 5 kV.
-
Insulation Resistance Measurement: Up to 10 TΩ at 5 kV.
-
Diagnostic Test Modes: Includes Insulation Resistance (IR), Timed IR, Dielectric Absorption Ratio (DAR), Polarization Index (PI), Step Voltage (SV), Dielectric Discharge (DD), and Ramp Test.
-
Short Circuit Current: 3 mA.
-
Noise Rejection: High noise immunity with 3 mA noise rejection at 5 kV.
-
Voltmeter Function: Measures AC/DC voltages from 30 V to 660.
-
Memory and Data Management: Advanced memory with time/date stamp, on-screen recall, and USB interface for data download to PC. Compatible with PowerDB Lite asset management software.
-
Battery and Power: Operates on a rechargeable lithium-ion battery with approximately 6 hours of continuous testing at 5 kV under a 100 MΩ load. Rapid charging capability allows for >60 minutes of testing after a 30-minute charge. Also operable from AC mains if the battery is depleted.
-
Safety and Durability: CAT IV 600 V safety rating up to 3000 m altitude. Features a dual-case design with an IP65-rated outer case for protection against dust and water, and a fire-retardant inner case for enhanced safety.

Usage/Application | Industrial |
Model Name/Number | Megger |
Measurement Range | 20 Ohm |
Display | Digital |
Test Voltage | 250 V (Min), 2500V (Max) |
The Megger MIT515 is a 5 kV digital/analog insulation resistance tester designed for high-voltage insulation testing in industrial and utility applications. It is particularly suited for testing equipment such as motors, generators, transformers, cables, and switchgear.
Key Features-
Test Voltage Range: Offers preset voltages of 250 V, 500 V, 1000 V, 2500 V, and 5000 V. Additionally, it allows user-defined voltages from 100 V to 1 kV in 10 V steps and from 1 kV to 5 kV in 25 V steps.
-
Resistance Measurement: Capable of measuring insulation resistance up to 10 TΩ at 5 kV.
-
Diagnostic Tests: Supports Insulation Resistance (IR), Dielectric Absorption Ratio (DAR), and Polarization Index (PI) tests.
-
PI Predictor Function: Includes a PI predictor (PIp) function that enables faster estimation of the Polarization Index, enhancing testing efficiency.
-
Display: Features a large, backlit LCD that displays multiple parameters simultaneously, including resistance, voltage, leakage current, capacitance, battery status, and time constant.
-
Power Supply: Equipped with a rapid-charge lithium-ion battery that provides up to 6 hours of continuous testing at 5 kV with a 100 MΩ load. The battery can be fully charged in approximately 2.5 hours. The unit can also operate directly from an AC power source if the battery is depleted.
-
Safety and Durability: Designed with a dual-layer case—an outer layer for impact protection and an inner fire-retardant layer. The tester is rated IP65 when the lid is closed, offering protection against dust and water ingress. It meets safety standards IEC 61010-1, CAT IV 600 V up to 3000 m altitude.
