The Megger S1-1068 features a measurement capability of up to 35 TΩ at a 10kV test voltage, which allows for testing highly resistive and modern electrical insulation designs.
Equipped with premium 8mA noise suppression and four select software filters (10s, 30s, 100s, 200s), the device effectively filters out external electromagnetic waves. This makes testing highly secure and stable even in crowded substations or heavy industrial sites.
The tester supports multi-faceted diagnostics of high-voltage systems. It has integrated configurations for Polarization Index (PI), Dielectric Absorption Ratio (DAR), Dielectric Discharge (DD), Step Voltage (SV), and Ramp diagnostics.
Yes, users can remotely interface with the device via an isolated USB link. For data transmission, both isolated USB cables and onboard Bluetooth technologies are fully supported.
The lithium-ion battery requires 2.5 hours to fully charge from empty. A rapid 30-minute quick charge session generates enough operating energy to complete up to 1 full hour of testing at 5kV with a 100MΩ load.
