Siemens Analog Counters/ Surge Counters monitoring devices, Air-insulated switchgear

We offer a complete line of monitoring devices Analog Counters Surge Counters, with a variety of innovative functionalities that can be perfectly matched to your requirements, ensuring that impending faults will be detected as early as possible and before the security of supply is compromised. Discover supply security at an entirely new level in our portfolio.

Monitors assist in the early detection of relevant arrester changes and support the security of supply. Siemens offers a range of control spark gaps and analog counters as well as digital and portable monitoring devices.

Analog Counters Surge Counters -Surge Arresters

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.

The 3EX5 050 surge counter with leakage current meter also monitors and displays the arrester leakage current.

In addition to the functions described here, versions 3EX5 030-1 and 3EX5 050-1 can also be equipped with a passive auxiliary contact for remote metering.

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.
The display unit also provides a connection for measuring the leakage current locally – for example, using an oscilloscope (measuring lead available as accessory).
