Overview

Megger MIT515/MIT1025 High-Voltage Insulation Resistance Tester (Discontinued by the Manufacturer)

Overview

The MIT515 and MIT1025 are Megger 5 kV and 10 kV digital high-voltage insulation resistance testers for insulation testing of cables, transformers, motors and generators. The Megger product page marks them as discontinued. Current 5 kV/10 kV models are the Essential series MIT515/2 and MIT1015 and the Advanced series MIT525/2 and MIT1025/2; specifications differ, and we can advise on replacement models.

Key Specifications

  • Test voltage: MIT515: 250 / 500 / 1000 / 2500 / 5000 V; MIT1025: 500 V–10 kV; both user-adjustable
  • Measurement limit: MIT515 10 TΩ; MIT1025 20 TΩ
  • Test modes: MIT515: IR, IR(t), DAR, PI; MIT1025 adds SV, DD, Ramp, plus memory and USB
  • Short-circuit current and noise immunity: 3 mA; noise rejection 3 mA
  • Safety and protection: CAT IV 600 V (up to 3000 m); IP65 (lid closed), IP40 (lid open)
  • Power: Li-ion 10.8 V 5.2 Ah, mains operation possible; MIT515 approx. 6 hours at 5 kV into a 100 MΩ load

Applications

  • Insulation resistance and PI testing of cables, transformers, motors and generators.

Specifications per the Megger product page and the MIT515/MIT525/MIT1025/MIT1525 datasheet; current models per the Essential series datasheet (V08) (retrieved 2026-10-21).
