Power plants and substations call for rock‑solid insulation checks. The Megger S1-568-UK 5kV High Performance Diagnostic Ins Tester meets that need, driving 250 V to 5 kV through critical assets while reading resistance right up to 15 TΩ. A rigid dual‑wall, flame‑retardant shell and an IP65‑rated seal keep out dust, rain and knocks, so you can keep testing when conditions turn rough.
Performance in hostile zones
An 8 mA noise rejection system, helped by four selectable filters, slashes interference from switchgear discharges and overhead lines. The tester sources a steady 6 mA short‑circuit current, then tracks leakage, voltage and capacitance on a bright back‑lit screen, so trends stand out at a glance. Timed tests, PI, DAR, step‑voltage, dielectric discharge and ramp routines run at the twist of a rotary switch, letting you build a full health picture in minutes.
Smart data handling
Onboard memory stores eleven hours of five‑second readings, complete with date and time stamps for simple proof of maintenance. Link by Bluetooth or the isolated USB port to view results live in PowerDB Lite or to run the unit remotely from a safe distance, cutting downtime when the yard is energised.
The closing lid locks water and grit outside while a long‑life rechargeable battery powers a full shift. With rugged design, clear controls and a full safety IEC 61010 Cat IV 600 V rating, the instrument keeps engineers productive and equipment protected. Use the tester with confidence wherever high voltage insulation needs clear, fast answers, and rely on the Megger name to back every measurement. The second appearance of the key phrase, Megger S1-568-UK 5kV High Performance Diagnostic Ins Tester, completes compliant optimisation without clutter.
