PART IV – ELECTRICAL WORKS

Unless otherwise indicated in the single items, all items listed below are intended to be furnished and installed, connected and completed with all the accessories necessary to furnish the equipment operating in a perfect manner.

It shall be the Contractor’s responsibility to perform installations and furnish materials that conform with Norms, Regulations and Italian Laws.

All materials shall bear the Italian Quality Mark.

All the electrical systems shall comply with CEI Norms and Law 37/08. All the machines, equipment and electric and mechanical components shall conform to D.Lgs n.17 dated 27 January 2010 concerning "CE" Mark.

At the end of the work, the Final documentation must be provided in separated set for each substation, including all AS BUILT drawings, equipments datasheets, files, tests reports, certifications, O&M manuals and warranties. A single document for all the substations will not be approved.

SAFETY

The project plans to repair the electrical system inside electrical substations, where the following electrical categories are present:

- cat. 0: less than 50 Vac, 120 Vdc

- cat. I: from 50 Vac up to 1,000 Vac and from 120 Vdc up to 1,500 Vdc

- cat. II: from 1,000 Vac up to 30,000 Vac and from 1,500 Vdc up to 30,000 Vdc.

The project doesn’t includes works to perform on live parts of cat. II system (medium voltage); only works on cat.

0 and cat. I live parts (low voltage) are approved. If the Contractor forecast to operate on low voltage live parts, a work-plan must be issued in accordance with the applicable safety codes and standards, expecially CEI 11-27 norm, Decree 81/2008 and amendments.

In general, to operate on the electrical parts of this project, live or dead type, skilled personnel are request and Contractors must submit declaration to demonstrate that the workers are authorized and have the ability to works on low voltage live parts (“PES” qualification).

The power outages for doing works in safety must be scheduled and coordinated at least 20 day before with 31st CES/CEO/CEOFE; the Contractor must specify which substation and equipment are involved, which is the scope of the outage (e.g.: replacement of the 20 kV relay, tests, etc.), the forecast time to start and finish the work.

The Aviano Air Base staff will be in charge to feed the buildings involved in the power outages for the time needed by the workers to perform all the activities.

The main safety rules to respect during the works follow:

- D.Lgs 81 (2008 and Amendments) Consolidated act for safety in the worplace

- D.Lgs 106 (2009) Supplementary and corrective provisions of the D.Lgs 81/2008 concerning the protection of health and safety in the workplace

- CEI 11-27 (2014) Works on electrical installations

All the works must be performed by the Contractor taking in charge the “responsibility of the plant” as defined by the CEI 11-27 norm. Prior to start the works, an official document will be issued to transfer the responsibility from the Aviano A.B. URI (Unita’ Responsabile Impianto IAW with CEI 11-27) to the figure identified by the Contractor in its organization. This figure will assume the role of “Responsabile d’Impianto” as defined by CEI 11-27 norm.

POWER OUTAGES

Works those involve/cause transformers/loads outages have to be performed during night shift (from 20:00 pm to 04:00 pm), holidays included. Works those not involve/cause transformers/loads outages can be performed during day shift.

3. RELAYS REPLACEMENT AND MAINTENANCE. Replacement of the existing out-of-service relays located on the 20 kV switchboards and ordinary maintenance of the functioning ones. The replacement includes furnishing and installation of each device and its associated auxiliary components, modules, cards, wiring connection, thresholds settings, instrumental tests, commissioning, to guarantee the fully

PHASE 2 – REVISION #2 SCHEDULE OF WORK ITEMS Page 26 of 52 restauration of the protection. The ordinary maintenance of the functioning relays (not subjected to replacement) includes the maintenance of the relevant auxiliaries, connections, circuits. The work includes testing of all the devices.

At the end of the work a Check List report must be delivered in accordance with the norms CEI 0-15, CEI 78-17.

The new relays must allow the measurement of phase currents I1, I2, I3 RMS, measurement of voltages, frequency, active and reactive power, residual current Io, average and maximum values. Storage of the values of the phase and homopolar currents before an intervention on an electrical fault. Possibility of supervising the protection via modbus connection through a modbus / ethernet gateway device. Unit must be tested in accordance with IEEE-693, for resistance to seismic risk up to class 2. For each relay, this voice includes the input/output module necessary to operate in the medium voltage system connected with SCADA. The voice includes all the accessories necessary for installation and any other charges to give the finished work in a workmanlike manner.

The relays must be capable of protection and measurement with a graphic LCD display.

The existing relays are based on Schneider Electric type models and they form a coordinate system of protections based on logical-selectivity through the Aviano Air Base substations. The following digital type of relays are included:

- SEPAM S42. The protection ANSI codes are: 50, 51, 51 N, I>, I>>, I>>>, Io>, Io>>, 67N-NI, 67N-NC and the directional phase over current code 67. Relays to be installed at Public distributor incomings shall be equipped also with protection functions 81H-81L 27-59.

- SEPAM S41. The protection ANSI codes are: 50, 51, 51 N, I>, I>>, I>>>, Io>, Io>>, Directional Earth Fault 67N-NI, 67N-NC.

- SEPAM S20. The protection ANSI codes are: 50, 51, 51 N, I>, I>>, I>>>.

- SEPAM T20 dedicated to the transformer protections. The protection ANSI codes are: 50, 51, 51

N, I>, I>>, I>>>, 49 RMS.

The Digital Relay manufacturer shall have a valid ISO 9001 certification and an applicable Quality Assurance and Quality Control system. The Digital Relay manufacturer shall have the Environment Certification ISO 14001.

Relay factory configuration to be suitable for Aviano AB MV system.

A test phase is included in the work to assess the rightness of the installations. As a minimum the following tests must be performed by the Contractor:

- Functionally test to ascertain the correct operation of the Input & Output digital contacts.

- Primary injection on the TA circuit by using a relays test-box (“cassetta prova relè”), to verify:

- the correct transformation factors;

- the correct reading of the injected current values by the relays.

- Verification of the correct thresholds settings by using a relays test-box (“cassetta prova relè”), with recording of the opening-times.

- Verification of the correct operation of the sending and receiving of logic blocks, performed by means of fault simulation.

Schedule of the tests and how they can be performed must be submitted by the Contractor and approved by the Project Manager.

Prior to any work the Contractor must submit a time-frame table to allows the Aviano A.B. to understand which loads will be affected by power outages.
