The basic version 3EX5 080-0 of the Siemens Energy device for basic arrester condition monitoring (ACM) provides a wide range of standard functions, including total leakage current measurement and display, surge current impulse metering and display, 3rd harmonic analysis of leakage current with compensation for network-dependent harmonics, temperature correction, and condition indication by means of LEDs in the colors of traffic lights.

If the basic version is already in use on a surge arrester, it is possible to upgrade to the advanced version using a USB wireless module, free software, and a specific access license, without having to modify the arrester. It then has access to the entire range of functions of this powerful monitoring system.

The ACM 3EX5 080-1 monitoring device features a wireless USB module to allow for direct, wireless communication with a PC or notebook.

You can use the USB wireless module (3EX5 086) and free “ACM Service Tool” software to connect the monitoring device and PC using the existing USB port. The Service Tool software makes it possible to display, analyze and evaluate the measured and calculated data on a PC. It can also be used to modify and store certain customer-specific parameters (surge arrester type, date/time correction, location, name, etc.) and perform software updates.

Equipment monitoring is a proven method for recording operating states and remaining service life, providing the operator with important data for asset management. Surge counters are a robustly constructed instrument suitable for installation in the earth connection of a surge arrester.
