Directive 2004/108/EC) and concerning electrical equipment for use within specified voltage limits (Low-voltage directive 2006/95/EC). This conformity is the result of tests conducted by Hitachi Energy in accordance with the product standard EN 60255-26 for the EMC directive, and with the product standards EN 60255-1 and EN 60255-27 for the low voltage directive.
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 Energy's recommendation is as follows: Every second to third year •...
Hitachi Energy 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.
An alternative is to open the IED and send only the faulty circuit board to Hitachi Energy for repair. When a printed circuit board is sent to Hitachi Energy , it must always be placed in a metallic, ESD- proof, protection bag. The user can also purchase separate replacement modules.
