Page 293: Commissioning And Maintenance Of The Fault Clearing System
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, Hitachi Power grids' recommendation is as follows: Every second to third year •...
Page 294: Visual Inspection
Hitachi Power grids protection IEDs are preferably tested by aid of components from the COMBITEST testing system described in information B03-9510 E. Main components are RTXP 8/18/24 test switch usually located to the left in each protection IED and RTXH 8/18/24 test handle, which is inserted in test switch at secondary testing.
Page 295: Self Supervision Check
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 Commissioning manual © 2017 - 2022 Hitachi Energy. All rights reserved...
