iso nh3 Measurement for high-voltage switchgear

Testing Iso Phase Bus (IPB) or the bus work within Switchgear (SG) cabinets, often several in series, is normally an AC Withstand test, where the test voltage is applied from bus to ground and held for 60 seconds. The insulators holding the bus off of ground are either good or defective.

The parts subjected to normal wear and agingneed to be serviced for ensuring full reliability of the operations. These parts may be mechanical components or electrical components. The interval at which the maintenance should be carried out depends upon the following factors: 1. The number of short-circuit interruptions 2. The switching frequency 3. The actual service time The actual conditions of use in terms of the frequency of operations, environment and severity of switching duty vary so much that it is impossible for the manufacturer to give detailed guidelines to the user concerning the frequency of maintenance.
