Please help me regarding my one concern. - During earth pit testing we noticed that the Clean earth pit and dirty earth pit showing continuity (Resistance value - 5ohm) . I want to know that if both earth pit have separate location and there is not internal looping between PIT then why such continuity is showing on it . Because of this issue the field side all earthing point showing short. In PLC panel we are providing two types of earthing cable which is coming from separate earth pit (Clean and Dirty earth pit) because of earth PIT showing short our PLC is not complying spec . please help regarding this issues.
1555For DG or Transformer body earthing, is it necessary to terminate the earth bus to earth pit directly? If not terminated to earth pit directly in earth pit and connected to any common bus strip which ultimately connects to earth pit, what will be the pros and cons?

When we use air circuit breaker, it has O/L protection ,time delay SC protection, Instataneous SC protection & ground fault protection. They all have some setting range. But what is the suitable/allowable setting for the above protection which will be safe for the equipment? For example-O/L protection setting have a range of (0.4,0.45,0.5,0.55,0.6,0.65,0.7,0.8,0.9,1.0)xIn Time delay SC protection have a range of (1.25,1.5,2,3,4,6,8,10,12)xIn Time delay setting is 0.02,0.1,0.2,0.3,0.4 Instataneous setting is fixed to 20xIn Gound fault setting is given 100A,300A,600A,900A,1200A This setting are for 2500A ACB. So what will be the basic allowable setting for the above protection? is there any formulae to calculate this<
