The Megger S1-1568/2-AU is an expert-grade 15 kV insulation resistance tester, engineered for superior performance and reliability in the most challenging high-voltage electrical environments.

It is the premier diagnostic tool for senior engineers, utility technicians, and maintenance professionals who require uncompromising precision for testing transmission-level assets, including transformers, bushings, and long cables. This instrument delivers the power and accuracy needed to ensure the integrity of critical infrastructure and support predictive maintenance programmes.

A key advantage of the S1-1568/2-AU is its industry-leading noise immunity, which effectively rejects up to 8 mA of interference. This ensures stable and dependable measurements in extreme EHV environments up to 765 kV, where electrical noise can render other testers ineffective. The addition of the patented RE>Act™ test mode further enhances measurement reliability by quantifying re-absorption currents, which prevents incorrect pass/fail decisions on insulation. This feature also improves operator safety by monitoring the discharge process after a test.

Combining a full suite of diagnostic tests (IR, PI, DAR, DD, PDC, SV), the S1-1568/2-AU provides a complete assessment of insulation condition. Its CAT IV 1000 V safety rating and rugged, dual-case design provide maximum protection for the user and the instrument.

Workflow is streamlined through on-board, time-stamped memory and remote operation via USB. Data can be transferred to the free CertSuite Asset Lite software, simplifying reporting and asset management. Powered by a rapid-charge Li-ion battery or directly from an AC supply, the S1-1568/2-AU provides the operational flexibility and performance required for critical high-voltage testing.
