Tenders are invited for new arc resistant switchgear (main switchgear) with equipment enclosure, equipment foundation for main switchgear, new connections to existing ameren transformers, new low resistance grounding system, replacement of medium voltage variable frequency drives (vfd~s) in pump station no.
The code which implements the methodology set out in the paper allows on the basis of the relevant electrical measurements to evaluate not only the resistance of the grounding of electrical devices, but also as its own and mutual resistance grounding all the electrodes in a three-electrode setup measuring the resistance of the grounding device.
However, high resistance grounding does not protect against phase-to-phase faults.
A more proactive approach is to lower the available incident energy by using circuit protection devices and high resistance grounding.
That's one reason why mines have adopted high resistance grounding, in which the neutral point is connected to ground through a resistor (see Figure 2) of value sufficient to limit ground fault current to a few amperes, generally 25 A or less, although a 5 A limit is typical.
