Investigasi Pengaruh Berbagai Faktor Eksternal terhadap Pembacaan Amperemeter Clamp_On

Clamp-on ammeters operat based on magnetic field induction, not connected electrically to the measured circuits. This instrument can measure and be removed without disconnecting the circuits. Thas, teh reading on their measurements is affected by some factors outside themselves. This research investigated some external factors those may affect the reading of clamp-on ammeter. The External factors were conductor cross-section, insulating size and material, type of load, metal cubicles and other circuit existences for various current magnitudes. The differences of reading were obtained by comparing the clamp-on ammeter measurement result to those the conventional ammeter. From the external factors, the largest influence was existence of other circuit line that pass by te clamp. The differece of reading had variation, depend on following current. Whereas the second largest was presence of cubcle cover the clamp, where the difference of reading had variation, depend on size of cubicle. The less of cubicle, the larger of difference of reading. While the influences of other external factors were relatively low, below 10%, with the reference on reading of conventional ammeter.
