This system is predicated on Ohm’s law, as well as the measurement principle typically consists of applying four aligned electrodes. Quite a few dispositions on the electrodes are possible, and Wenner’s one particular is the most typical electrode spacing procedure.
The resistivity with the soil is one of numerous components that influence the assistance lifetime of a buried structure. Soil resistivity may perhaps affect the material range and The placement of the structure.5
This paper determines the possibility of a back again flashover for many combos of lightning strokes and earthing profiles. Tower Footing Resistances as little as nine.eight Ω can cause back flashover, offered the lightning stroke exceeds 12 kA. On top of that, the paper provides and discusses an modern hybrid electrical power line protection plan, which estimates and considers the superior Charge related to establishing an earthing system; it examines the impracticality of re-engineering an earthing plan for implementation and final results acquired through the inclusion of lightning surge arrester's (LSA). The fee-saving ensuing from dips is likewise proven more than twenty five many years for an 88 kV line, and the breakeven issue is recognized. The final results confirmed that the best state of affairs might be to reduce the tower footing resistance to 29.one Ω and set up eleven LSA for each period.
Purpose: High-voltage electrical devices requires a grounding set up in order to shield life in freshwater swamps which has a hydrogen opportunity of 6.seventy five. To make a grounding structure, it is needed to understand the resistance worth and grounding materials, particularly copper-coated rod electrodes at various depths. Analysis methodology: The analysis was conducted inside of a freshwater swamp near the shampooing substation making use of discipline observations and immediate measurement of soil resistance values, followed by a literature evaluate and comparisons working with COMSOL simulation and FEM Analysis. Results: The final results of direct investigation and simulations suggest that if you want to perform a grounding resistance value < 5 ohms according to the PUIL 2011 normal for only one rod technique manufactured from copper, it is necessary to improve the depth from the grounding electrode within just a range of ten meters, which differs through the simulation success of ground resistance measurement as well as Comsol software.

Figure one: Wenner 4-pole strategy Earthing Solutions employs the Megger DET4TD, a hardwearing and dependable testing device. The Megger testing unit is intended to be self-checking to allow the operator to deal with collating and understanding the final results.
Whilst Soil Resistivity Testing Solutions Bangladesh a comprehensive soil testing program could possibly be warranted, specially when carrying out failure analysis, for most environments the soil resistivity testing data gives An impressive foundation for assessing soil corrosivity. Below is an average chart correlating soil resistivity with soil corrosivity.
Hence, it is important that the CP designer have accurate info around the soil ailments at both equally the construction and at any proposed anode method destinations. The shortage of ample soil resistivity info can render a cathodic protection procedure (CP program) layout ineffective and may lead to costly remediation efforts in the course of commissioning.

Tower footing resistance must be retained uniform and as reduced as you possibly can to forestall back flashovers over the insulator beneath lightning situations. Theoretical simulations have been conducted on the various methods that exist to Enhance the tower footing resistance values. A scenario review was carried out to confirm the tower footing resistance of the 88kV Eskom line. The crows earthing configuration was then used to decrease the footing resistance to a value lower than 30 ohms. Final results acquired are presented and talked about.
