Advanced 5 kV, 10 kV and 15 kV insulation resistance testers

Megger offers three insulation tester ranges: Essential, Advanced, and Expert. 

• Choose Essential for go/no-go testing where storage isn’t needed — ideal for basic maintenance.

• Choose Advanced if you need deeper diagnostics and onboard storage, but not remote control.

• Choose Expert if you work in noisy substation environments or need full remote testing.

Once you’ve selected the right level, simply choose the test voltage (5, 10, or 15 kV) for your application. 

Yes. The Advanced range features built-in memory and USB connectivity as standard, plus optional Bluetooth®. Test results can be exported directly to PowerDB or CertSuite to support documentation, compliance, and long-term record keeping. 

All Advanced models support a full suite of diagnostic test modes, including IR, DAR, PI, DD, step voltage, ramp, and PDC (with software). These tests are essential for in-depth insulation condition assessment on critical assets like transformers, cables, motors, and switchgear. 

Yes — the Advanced models offer 6 mA of noise immunity, making them suitable for environments up to 230 kV. This ensures stable, reliable results in moderately noisy conditions, such as industrial plants or distribution-level substations. For extreme electrical noise or testing above 230 kV, the Expert range is recommended.

Re>Act Mode monitors reabsorption current after an insulation resistance test, so you can see when insulation is ready to retest. This helps reduce false readings caused by residual current and gives you more confidence in the next result.Relevant ranges: All.

Re>Act Mode helps reduce the risk of dangerous return voltages after a test. It shows whether reabsorption current is still present, helping users confirm when the asset is in a safer condition before disconnecting or retesting.Relevant ranges: All.

Yes. Re>Act Mode can reduce retest waiting time by showing when the asset is actually ready for the next test.This helps teams keep work moving without relying only on fixed discharge times.Relevant ranges: All.

PI Predictor™ estimates the Polarisation Index (PI) value before the full PI test has finished. This can reduce PI test time by up to 50%, helping teams make faster decisions when testing multiple assets.Relevant ranges: All.

Use PI Predictor™ when you need faster PI insight during routine testing. It’s especially useful when testing multiple motors, cables, or transformers and you need to reduce site time without losing diagnostic value.Relevant ranges: All.

PDC stands for Polarisation Depolarisation Current testing. It measures charging and discharging current behaviour to give deeper insight into insulation condition, including moisture, ageing, and contamination.Relevant ranges: Advanced and Expert.

Not always. Routine maintenance often starts with insulation resistance, DAR, and PI tests. PDC is more useful when results need further investigation or when you need deeper condition assessment on critical assets.Relevant ranges: Advanced and Expert.

CertSuite Asset is a software for managing asset and test data in a structured, auditable way.It helps teams store results, track asset condition over time, and support reporting and compliance.Relevant ranges: Advanced and Expert.

No. Essential instruments don’t include internal memory or data export. If you need export to CertSuite Asset, you should choose an Advanced or Expert model.Relevant ranges: All.
