On 21 March 2016, a PET® MINI 210o electrical substation was installed at Panorama Hotel in Češkovice, a municipality located close to the Moravian town of Blansko.
The substation had been transported directly from Brno exhibition grounds, where it was on display at the booth hired by EEIKA Brno, s.r.o. for the duration of AMPER, a well-recognized international trade fair of electrical engineering. The product is characterized by a fire-resistant door of the lv switchboard. Similar doors were previously fitted in selected PET® substations to protect the surrounding area, including the actual transformer shelter, from any fire caused by possible malfunction of a substation component. In this system, however, the conditions are different: the station is positioned in the risky environment of a new graduation tower, where therapeutic aerosols are inhaled. As the north-eastern corner of the substation lies only within 2.75 m from the tower, the entire system would be exposed to direct heat emission if fire broke out, with the lv switchboard accessible through the eastern door in immediate danger. Thus, the switchboard is protected by an EI-15DP1 fireproof element made of a welted, sealed steel sheet and inside sandwich panels (mineral wadding, non-flammable panels, and steel cover of 1 mm in thickness); the door is capable of resisting a fire for at least 15 minutes.
The substation comprises a 160 kVA, oil-filled transformer, an ORMAZABAL GA 2K 1TS hv switchgear (owned by the E.ON company), an RBTR 0640/44(6)35 lv switchgear, and an SOM measurement control case.
