Megger MIT1525 15kV Insulation Resistance Tester Rugged IP65-rated design with dual-case protection

Description

The Megger MIT1525 is a high-performance insulation resistance tester designed for professional use, completing Megger’s range of high-voltage MIT testers. With an output of up to 15kV DC and the capability to measure insulation resistance values as high as 30TΩ, the MIT1525 is the ideal tool for advanced insulation testing across a variety of industrial applications.

Comprehensive Testing Capabilities

The MIT1525 offers a versatile array of testing modes to suit any insulation diagnostic requirement, including:

• Timed Insulation Resistance Testing
• Polarisation Index (PI)
• Dielectric Absorption Ratio (DAR)
• Step Voltage Testing
• Dielectric Discharge (DD)
• Ramp Testing

Step voltage testing is particularly useful to assess the insulation and cables’ ability to withstand day-to-day voltage spikes, such as those generated by motors in operation. The MIT1525 allows fine-tuned step-voltage adjustments: 25V increments between 1kV and 5kV, and 50V increments between 5kV and 15kV.

Enhanced Data Management

The MIT1525 features an advanced internal memory system with time and date stamping, allowing users to store up to 5.5 hours of measurements taken at 5-second intervals. Data can be reviewed directly on the large backlit screen or exported to a PC using the included Megger PowerDB Lite software via USB for live-time analysis and reporting.

Designed for Ease of Use and Durability

With its dual rotary switches, the MIT1525 is intuitive to operate, even in demanding environments. The large, backlit display simultaneously shows critical testing parameters such as:

• Resistance
• Voltage
• Leakage Current
• Capacitance
• Battery Level
• Test Time

The rugged dual-case design provides excellent protection from impacts and is fire retardant, ensuring long-lasting reliability. When closed, the lid creates a secure seal offering IP65-rated moisture and dust resistance, making the MIT1525 suitable for use in harsh environments.

Power Options and Calibration

The instrument operates on a rechargeable Li-ion battery or AC mains supply, offering flexibility for field and workshop use. Each MIT1525 comes with a calibration certificate as standard, ensuring precise and reliable measurements.

Why Insulation Resistance Testing Matters

Insulation can degrade over time due to factors such as temperature, current flow, physical wear, chemical exposure, and environmental conditions. Regular insulation resistance testing is crucial for maintaining both the safety and reliability of electrical installations, helping prevent costly failures or hazards in service.
