The periodicity of all tests depends on several factors, for example the importance of the installation, environmental conditions, simple or complex equipment, static or electromechanical IEDs, and so on. The normal maintenance praxis of the user should be followed. However, ABB's recommendation is as follows: Every second to third year •...

When the protection IED undergoes an operational check, a tripping pulse is normally obtained on one or more of the output contacts and preferably on the test switch. The healthy circuit is of utmost importance for the protection operation. If Transformer protection RET670 2.2 IEC Commissioning manual...

The neutral-point voltage to an earth-fault protection IED is checked. The voltage is normally 0.1 to 1V secondary. However, voltage can be considerably higher due to harmonics. Normally a CVT secondary can have around 2.5 - 3% third-harmonic voltage. Transformer protection RET670 2.2 IEC Commissioning manual...
