CONTROL SPARK GAPS
Slide 1 of 1
Control spark gaps 3EX6 040 and 3EX6 020
The control spark gap 3EX6 040 is a monitor for surge arresters that is integrated into the arrester’s ground wire. It counts the surge arrester responses that have occurred and allows an estimation of the current flowing through the surge arrester based on characteristic burn marks.
Spark gap 3EX6 020 has a remote display with an optical connection.
ANALOG COUNTERS

Surge counters
|
The 3EX5 030 surge counter is a traditional monitor for surge arresters. It is integrated into the arrester ground connection and counts the surge arrester responses that have occurred. |
Counter for remote monitoring 3EX5 060/62
|
The 3EX5 060 sensor is a surge arrester monitor that is integrated into the arrester ground wire. It counts the surge arrester responses that occur and continuously measures leakage current. The 3EX5 062 display visualizes the surge arrester responses detected by the sensor and the leakage current at a convenient location. The display can be installed at a distance of up to 200 meters. |
DIGITAL MONITORING
ACM-basic 3EX5 080-0
The basic version 3EX5 080-0 of the Siemens 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.
ACM-advanced 3EX5 080-1
| 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. |
PORTABLE MONITOR
Slide 1 of 1
Live Condition Monitoring with LCM 500
The LCM 500 is a portable measuring system for metal-oxide surge arresters that measures the 3rd harmonic component of the leakage current without interrupting operation.
The data obtained on the calculated resistive leakage current can provide valuable information on the condition of the arrester.
