- 5 kV, 10 kV, or 15 kV
- Measures up to 30 TΩ
SKU
MEG-MIT-ADV
The Megger Advanced Range includes three models with maximum test voltages of 5 kV, 10 kV, and 15 kV. They include standard insulation resistance (IR), dielectric absorption ratio (DAR), and polarisation index (PI) testing, dielectric discharge (DD), step voltage (SV), and ramp voltage tests.
When paired with PowerDB software, they also support polarisation/depolarisation current (PDC) analysis, facilitating advanced diagnostic workflows usually reserved for higher-end systems. Each model has onboard memory and USB connectivity for exporting data to Megger's PowerDB or CertSuite Asset software platforms.
The Advanced Range has patented PI Predictor technology, which can reduce traditional PI test durations by up to 50%. They also include precision guard terminals that maintain accuracy even in the presence of high surface leakage, along with high noise rejection of up to 8 mA, and can perform effectively in environments up to 1000 kV.
