The Fisher Pierce Series 1301 high accuracy line post current sensors provide a reliable measuring method for distribution systems from zero to thousands of amperes. The current sensors may be used for capacitor switching, load surveying, or protective relaying. The sensor consists of a porcelain line post insulator with an embedded coil that is inductively coupled to the conductor. The voltage induced in the coil is directly proportional to the alternating current in the primary conductor.The Series 1301 high accuracy sensors may be used with the Series 4400/4500 AutoCap Capacitor Controllers for Var or Current control applications. The sensor offers a unique combination of safety, installation without service interruption, space saving, and low installed cost. |

 |
No Service Interruption/Revenue Loss | |
| Line cutting or dead ending is not necessary for installation because any nonferrous conductor-tie material can be used to fasten the conductor to either sensor. | ||
|
No Maintenance | |
| Rugged, porcelain housing with no moving parts allow sensors to withstand continuous high current, transients, and switching surges. | ||
|
Large Operating Range | |
| The sensor never needs to be changed as loads increase. | ||
|
Safety | |
| Low output voltage (only 1 volt for each 60 amperes of line current) eliminates dangerous shock hazard. | ||
|
Easy Installation | |
| Low cost, space saving installation without service interruption. | ||
