·         As per the Preventive Maintenance schedule,  Engineer informs Powerhouse and  allot Technicians
·         Get the work permit from Engineer.
·         Necessary PPE’s to be used for PM activities.
·         Check the condition of Earth resistance Meter  and it working properly
·         Arrange the two electrode  for Earth pit checking
·         Check the tightness of Connection and clean the Earth Pit
·         Connect the equipment  as per Fall of Potential method
·         Taken Earth resistance value When Grid Connected(below 2 Ohm)
·         Taken Earth Resistance value when Grid disconnected(below 5 Ohm)
·         If  Earth resistance value is low , adding water and salt in the Pit
·         After completion of the PM work, the same should be communicated to respective area Engineer
