Premise
Although the functions hosted (schools and convent) need to more important powers which exulate from the typical parameters of a house (which typically has a 3kw contract) as such is the conservatory always treated. Accomplice of this simplistic vision two factors:
- The nuns living them at the conventual level, have always considered their home conservatory (correctly) and if a house why not treat the electrical system as in all other houses?
- The conventual premises although they can be large and host many people as a hotel, thanks to the agreements taken between the State and the Church, dating back to the Lateran pacts, these institutions continue to enjoy an autonomy that allows them to have no specific obligations or specific laws to be respected on the firefighting and safety.
The activities present (pursuant to firefighting and VVF)
They counterbalanced this conduct, guaranteeing some minimum electrical safety levelsthe other two activities: the school and thermal power plant.
These two functions are in all respects two activities subject to the controls of the Fire Brigade pursuant to Ministerial Decree 151/2015 (School Activity 67, thermal power plant Activity 74). In the fire strategy, pursuant to the general rules called by the current anti -center code (RTO pursuant to DM 3 August 2015 and SMI) in point 10 of the fire strategies it is established that the technological systems in buildings, in order to avoid accidents must be designed and maintained in a workmanlike manner.
In particular in the premise, the first system that is prescribed to consider, is precisely that for the transport, distribution and use of electricity.
The assignment
The conservative body sensitized on the subject, in 2021 he decided to start a Global power of the electrical system In order to guarantee all the security requirements he needs. It also decides to start a restructuring of the system Also in order to divide the lines of supply of electricity, in order to proceed more easily to the distribution of consumption between school and convent. Division of expenses that are no longer procrastinable given the takeover of the Don Renato Fissi Foundation in 2020 in the management of school activities.
This will materializes in the professional assignment to the undersigned (Architect Enea Pacini, from home without Gas Tuscany, editor’s note)to carry out a project renovation project, for the purpose of securing it, to equip it minimum appliances needed to carry out the consumption monitoring.
I am also applying to carry out one lighting assessment on the classroom lighting system and develop a project for the replacement of the current neon lighting system in other more efficient with LED appliances.
The state of the initial places
From the documentary point of view, only the Project of the electrical system of the thermal power plant. Now obsolete project since the picture had been modified several times.
Carried out the first inspections, I discovered to be present within the Conservatory 24 electrical panels. The problems were manifold. On the one hand there is the lack of organicity. On the other hand, gradually I made the reliefs I started to realize that different magnetothermic switches was now obsolete And I found with the multimeter that several differentials were no longer able to release the current in the event of contacts (direct or indirect).
The sections of the conductors in various cases they were not related to the current named of the interruption (according to the well -known IB report
The intervention
The complex is large and the conservatory body has, every year, of limited resources To proceed. The proposed intervention project was carried out with the logic of Divide the upgrade to standard in various lotsin order to distribute the expenses In several years, giving priority to situations to be remedied considered more dangerous.
The calculation of the processes was divided following the same logic:
- Lot 1 – General dorsal standard and school system
- Lot 2 – Mass Electrical System Standard Conventual Spaces
- Lot 3 – Lighting adaptation to the legal parameters
The general electrical panel has been renovated by rationalizing it with the clear subdivision between schools and conventual spaces. In this switchboard, appliances were also put to analyze the network and consumption. A valley was made general picture schools that allow the deactivation of the supply of electricity in the event of an emergency. The main paintings were segregated with key.
In all the switchboards I have been replaced magnetothermic and differentials not working. Taking care to correlated nominal current of switches correctly with the conductors’ doors. The Interruption power (ICU, ICN) It was correctly correlated to the distance from the delivery point by evaluating the reduction of the short circuit current in relation to the length of the lines. The most dangerous situations related to the lack of grounding in terminal circuits will soon be arranged. Once this is done, I account to close the works and proceed to issue the declarations of conformity (Di.Co. pursuant to DM37/08) by the installation companies.
The adaptation of school lighting is scheduled for the next summer break.
