In many applications, ranging from circuit breaker tripping systems to uninterruptible power supplies for data and telecommunication installations, storage batteries are used as a standby power source.

Storage batteries play an essential role in many sectors of industry and commerce, not least as convenient sources of standby power. All too often however, stationary battery systems are installed and forgotten

In the manufacture and maintenance of wind turbines, low resistance testing is essential to verify the continuity of the lightning protection conductors in the turbine blades.

The objective of all circuit breaker diagnostic testing is to detect defects before they cause damage and system outages. Many test techniques are used to achieve this, but one that receives less attention than it deserves is vibration testing.
