INTRODUCTION
| MEWOI3100D+ Clamp Earth Resistance Tester is widely applied in ground resistance measurement, loop resistance measurement in fields such as electric power, telecommunications, meteorology, oil field, architecture and industrial electrical equipment, etc. When measuring ground system with loop, there is no need to disconnect the ground wire without auxiliary electrode, which means safer and faster. MEWOI3100D+ Clamp Earth Resistance Tester can measure the ground fault which can not be measured by traditional method, can apply in the occasion where traditional methods are unworkable; MEWOI3100D+ Clamp Earth Resistance Tester measures the integrated value of ground resistance and resistance lead. What's more, MEWOI3100D+ Series tester can measure the leakage current of ground wire. |
APPLICAITON
Why earth resistance can be found by only clamping it?
| Rx, is defined as earth resistance under test, and R1, R2... Rn are defined as earth resistance of other measuring objects. |
|
These earth resistances, R1, R2, Rn can be considered that they are connected in parallel. And they can be regarded as a combined resistance Rs. The Rs can be regarded small enough against Rx since a combined resistance consists of several resistances. Following is an equivalent circuit diagram of this circuit. |
|
Voltage V is applied to the object (Resistance Rx) measured from the voltage injection transformer CT1, and the current I corresponding to the earth resistance is flowed. The current I is detected with detection transformer CT2, and object (Resistance Rx) measured can be put out by the calculation. (refer to the right diagram) |
