Yes it should be disconnected from service. If the voltage is more than 10 it will destroy the meter and also give false reading. Please read the user manual reg the max voltage limit that the meter will work safely in energised service without disconnection.

May i know why the cable for current is longer than the voltage?

@raemondbradford1629 2 жыл бұрын

When current is injected into the earth, then the voltage will change around the location of injection. The voltage reference cable spike needs to be some distance from the points where current is injected or removed, in order to try and find a location with minimal disturbance of earth voltage potential.

Hi sir I have a doubt. Could you please tell me the difference between 2 point, 3 point method. In megger it has 4 terminals C1, C2, P1, P2. how to measure earth pit resistance?

@30mAkills Жыл бұрын

Short C1 and P1 and connect to electrode under test. P2 is for potential and C2 is for current spike. This is known as 3 point or Fall of Potential method. 4 terminals method is for testing soil as per Wenner method. This is for civil guys and not for electrical guys. Reg 2 point earth pit resistance testing: In India we don't/cant use this method because our public water supply is thru PVC pipes which is non conductor. Hope this helps.

Eg.: If 1 st electrode buried depth = 3 M then second electrode should be installed at a distance of minimum 6 M away and both should be linked with wire or strip at the top. 3. Wet the pit by watering because dry earth is a bad conductor. Note : Chemical electrodes are fraud work. Hope all this helps.

@30mAkills Жыл бұрын

Thumb rule for current spike distance from electrode = Minimum 8 to 10 times the buried depth of earth electrode. Eg., If earth electrode is 3 M long then C spike should placed about 24 to 30 M distance. This is to avoid '"zone of influence"' factor. Most manufacturers wont tell this because the distance will affect their tester sales in city and town areas where space is congested. So they suggest 5 M and 10 M which will not yield correct value. I challenge Kyoritsu in this matter.

One terminal of the bulb is connected to live (hot), the other to earth and the current is measured. Divide voltage by current and subtruct the bulb's resistance and the result is the earth resistance. What is wrong in such approach?
