Ultimate Generator Maintenance Guide: Inspections, Diode Testing & Insulation Resistance

Описание: Master the essentials of diesel generator maintenance with this step-by-step guide. Whether you are a technician or an operator, this video walks you through the critical procedures to ensure your CAT genset runs reliably.

In this video, you will learn:

✅ Daily Inspection: Essential visual checks for leaks, fluid levels, and belt tension.

✅ Internal Inspection: Checking connection bolts, cables, and exciter windings for heat damage.

✅ Diode Bridge Testing: How to use a multimeter to test rotating rectifiers and varistors.

✅ Insulation Resistance (Megger) Test: The correct procedure for testing stator windings, including safety disconnects for the AVR.

⚠️ Safety Notice: Always follow Lock Out / Tag Out (LOTO) procedures. Disconnect batteries and ensure the engine cannot start. Always disconnect electronic controls (AVR) before performing high-voltage insulation tests.
