Practical guidance on keeping substation equipment in service: infrared thermography and what NFPA 70B now requires, DC battery installation and NERC PRC-005 maintenance, vacuum breaker leak testing, and transformer winding tests. Each article explains the method, the standard behind it and how often to do it, so maintenance plans are built on evidence rather than habit.
