Spekifikashin

Yan yawan ground resistance da soil resistivity?

Yawan Ground Resistance:

• Four-Terminal Method: UT572 tana amfani da four-terminal method (ko kuma Kelvin method) don yawan ground resistance. Wannan ita ce ne ake yi da two auxiliary electrodes (auxiliary current electrode da auxiliary voltage electrode) da ground electrode under test don yawan.

• Current Injection: Tester ya saka wani frequency current a cikin ground through the auxiliary current electrode.

• Voltage Measurement: Voltage drop an buga saboda current ta measured through the auxiliary voltage electrode.

• Resistance Calculation: Yawan ground resistance value ya faru based on the measured current da voltage drop.

Yawan Soil Resistivity:

• Four-Terminal Method: Four-terminal method tana amfani da shi, wanda ke yi da four electrodes (two current electrodes da two voltage electrodes) don yawan soil resistivity.

• Current Injection: Current an saka a cikin soil through the current electrodes.

• Voltage Measurement: Voltage drop an buga saboda current ta measured through the voltage electrodes.

• Resistivity Calculation: Soil resistivity ya faru based on the measured current da voltage drop.
