About the product
The range includes three models: S1-568/2 (5 kV), S1-1068/2 (10 kV), and S1-1568/2 (15 kV). All are trusted by utility engineers, OEMs, and commissioning teams working on critical assets like transformers, cables, switchgear, and bushings.
The adaptive filter, nearly unique to Megger, monitors the rate of change in noise current and applies dynamic damping to prevent test current distortion. It predicts spikes that would otherwise affect results and stabilises readings — even during energisation events or switching noise.
Test modes include IR, DAR, PI, DD, SV, ramp, and PDC (with software). PI Predictorâ„¢ reduces Polarisation Index test time by up to 50%, and RE>Actâ„¢ shows when insulation is safe to retest, saving time and reducing risk.
Fully remote control via Bluetooth® or USB enables testing from a safe distance — or even from the comfort of an air-conditioned vehicle during extreme site conditions. Onboard memory and no-dongle Bluetooth® make data transfer seamless. High-performance guard terminals ensure measurement accuracy even with high surface leakage.
With CAT IV safety ratings, robust design, and powerful time-saving tools, the Megger Expert range gives HV professionals the speed, safety, and confidence they need to test without compromise.
