		abstract={Lightning Arrester is a channel guard against lightning strikes so that the Lightning 
Arrester isolation and grounding must be in good condition in order to protect the 
generation equipment. The PLTM Lambur transformer is a vital piece of equipment 
where safety must be maintained. On this basis, lightning arresters must comply with 
standards by testing insulation resistance and earthing resistance. In the insulation 
resistance test at the bottom-ground points the values were 0.2 M?, 0.07 M? and 0.4 
M?, at that point they did not meet the minimum value standard (> 1 M? / 1 kV) because 
the mount on the lightning arrester was cracked and needed replacement. After replacing 
the lightning arrester holder, the results of testing the insulation resistance at the bottom?ground point at the R phase of 76.8 M?, the S phase is 141 M?, and the T phase is 96.4 
M?, it can be seen that the insulation resistance at the bottom-ground point is already in 
good condition. well and above the minimum standard value. The results of the grounding 
resistance test, namely the phases R 7 ?, S 7 ?, and T 6 ? based on the value of the 
insulation resistance, do not meet the standard where the value is > 5 Ohm, and grounding 
roads must be added so that the value meets the standard, so that after adding grounding 
rods the value in phase R 1?, S1 ?, and T 1? based on the insulation resistance value 
meets the standard where the value is < 5 Ohm.}
