Online 3 Ph LA Tester   

(with wireless E sensor and current measurement) 

KPM’s  3 Phase Lightning Arrester Tester (KPM LA-103+) is the special instrument to be used to detect the electrical properties of Lightning Arrestors (LA/MOSA). KPM LA-103+ is capable of testing LA  online using six main methods as per IEC -:

​

1. Large-screen LCD display, full English menu operation, easy to use.
2 Using high-precision sampling and processing circuits, advanced Fourier harmonic analysis techniques to make data reliable .

3. The instrument uses voltage and current signals directly captured and inputted by a unique high-speed magnetic isolation digital sensor to ensure the reliability and security of data
4. This equipment can use induced electric field or wireless transmission method instead of PT secondary wiring.
5. The instrument don't need to connect PT secondary, and can measure resistive current directly.
6.There are six testing methods, providing a lot of choices for on- site person.( PT secondary method, induction method, wireless transmission method, a single current synchronization method, pt secondary synchronization method )
