Surge Counter
Our Surge Counters, with or without leakage current measurement, can also help to detect early malfunctioning before it leads to the threatening of the security of supply.
Our surge counters are fully tested for use with any manufacturer’s surge arresters to provide a comprehensive monitoring system.
These instruments, which require no auxiliary supply, are designed for
installation in the earth connection of a single surge arrester, or alternatively,
the DCC 2 may be used with the common earth of a three-phase set.
Fully weatherproofed and sealed for life, they are housed in a one-piece casted aluminum case
The glass viewing window is sealed in place, using a silicon rubber adhesive.
Mounting is effected by means of an integrally cast lug at the rear of the case providing a single clearance hole for the galvanized steel M12 bolt supplied. A fixing angle can additionally be installed by screws 2xM12x25.
DCC 2 and DCC-M2 use service-proven electrical circuits.
No special maintenance or service apart from general cleaning of the glass viewing window and the molded epoxy resin line terminal bushing is necessary.
