| Use advice for data set | The life cycle analysis of the RTXP 18 follows a “cradle to grave” analysis and covers the following life cycle stages: manufacturing stage (A1-A2), including the relevant upstream process (e.g. acquisition of raw material, preparation of semi-finished goods, etc.) and the main manufacturing and processing steps (A3); distribution stage (A4); installation stage (A5), including the relevant steps for the preparation of the product for use; use stage (B6) over reference service life (RSL) associated to the reference product; and end-of-life stage, including the necessary steps until and for the final disposal or recovery of the product system (C1-C4, D). |

The test switches can also be used for other testing needs not directly associated with relays, such as for switchboards or voltmeters. The test switch is especially suited for use where testing requires disconnection of the instrument transformer’s secondary or control wiring. It may also be used to advantage in the testing of other complete relay systems, even when each individual relay has its own test switch. When the test-plug handle is inserted into the test switch, preparations for testing are automatically carried out in the proper sequence, i.e. opening of tripping circuits, short circuiting and then disconnection of CTs, opening of voltage (VT) circuits and making relay terminals available for secondary injection. The test-plug handle may be connected to any type of test equipment or instrument. When a number of protection relays of the same type are tested, the test-plug handle need to be moved only from the test switch of one relay to the test switch of the other, without altering previously made connections. If different types of relays are to be tested, it is a simple matter to change the connections on the test-plug handle and the relay testing set. The COMBITEST system comprises of the test switch RTXP, the test-plug handle RTXH and the block-plug handle, RTXF. These are designed in three different versions equipped with either 8, 18 or 24 contacts. Together with the test leads, the trip-block plug RTXB, and an ammeter test-plug RTXM, the COMBITEST forms a complete system for the fast and safe testing of protection relays. The test switch, RTXP, is built up in a light beige housing containing a number of contact units. The contact units are of two basic types. One type is for trip circuits and designed to open first and close last when the test handle is inserted respectively pulled out. The other type is used for all other circuits, current, voltage and auxiliary power. If the housing is not fully equipped with contact units, unused space is occupied by dummies of the same shape as the contact units. The test switches are available with different contact arrangements. The test switch RTXP 18 contains 18 contact units and occupies two seats in the COMBIFLEX system with dimensions of 4U and 6C. It mounts directly on to the COMBIFLEX apparatus bars. |

| General comment on data set | Data quality: Specific data for the product composition are provided by the manufacturer. The data represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on EPDs according to EN 15804 and different LCA databases. The data quality of the raw materials in A1 is presented in the table below. Both primary and secondary data were used in the construction of the RTXP 18 LCA. Primary product data was collected from the bill of materials, technical documentation and supplier input, and primary assembly site data was collected from Hitachi Energy’s environmental performance database. Production site data was from 2023, and all production and technical data were collected during 2025. Secondary data supplemented the primary data for upstream material production and manufacturing, transport, use phase and end-of-life processes, as well as defining resource flows such as electricity mixes. The main database was ecoinvent, supported by other sources and all secondary data was compiled by LCA.no. Allocation: The allocation is made in accordance with the provisions of EN 15804. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances. |
