With the increasing dependency of back up systems on battery strings, and the escalating cost of replacing batteries, instrumentation and software systems that can measure, trend and manage the life-cycle of cells is a cost effective option.
There are two methodologies for testing batteries.
The first, impedance testing is an on line test and can be performed frequently to identify individual weak cells before they fail.
The second, battery discharge test is, normally, an off-line test and tests the actual output of the whole battery under load conditions. This will show what will actually happen if the battery is required to take the load.
Most battery systems are floating and have earth leakage monitors and trips if there is an earth fault. The Battery Ground Fault Tracer allows you to trace a faulty circuit easily in a complex floating system.
Power cable fault locating and testing takes on a whole new dimension with the modular cable fault locating concept from Megger. We have geared our development to the industry requirements for a more tempered fault locating method and have developed more sophisticated methods that reduce the stress on insulation systems.
Megger's thermal cameras are professional and easy-to-use, and provide fast accurate readings.
They can cover a wide range of surface temperatures with on-screen spot as well as max/min temperature measurement and tracking.
Our cameras also combine a visual and full infrared image on screen, making troubleshooting and pinpointing problems much easier.
