    the readings by sticking them into the soil about two or three inches deep. If you go five or six inches deep, after taking readings at two inches deep, the A.C. voltage, at the deeper point, will likely provide a significantly higher reading, which could temporarily mislead you into thinking the fault point is closer than it actually is.

    1.5 – OTHER READING TECHNIQUES Two other techniques you may choose to use in locating the point of the fault are: 1.5.1 - THE TRIANGULATION TECHNIQUE Now let's look at Figure 3. You will notice that it is essentially the same as Figure 2 but another set of readings is shown.

    to continue taking readings. If you go far from the starting location without getting any readings you probably should go back to the 2/3's point, to start again, and probe in the other direction. Remember that as you get close to the source transformer (into the transformer zone) you will begin to get readings due to the a.c.
