Surge counter EXCOUNT-I

A surge counter with basic leakage current measurement function

EXCOUNT-I is capable of  sensitively registering surges in combination with total leakage current. The values are shown digitally on an electronic display.

EXCOUNT-I measurement of total leakage current  is initiated by triggering a light sensitive diode on the sensor using a standard laser pointer. Without risking personnel safety this will initiate EXCOUNT-I to thereafter display the average value in milliampere.
 

Applications

  • For use with all makes and types of gapless arresters

Why Hitachi ABB Power Grids?

  • Proven safe short-circuit design 
  • No voltage added to the residual voltage of the arrester 
  • Able to detect lightning surges as low as 10 A
  • Toggle function between surge count and leakage current initiated by LED-pointer
  • Maintenance free
  • Easy to install
  • Easy to read from a safe distance
