In accordance with theharmonization agreementreached by the countries ofthe European Community,their national specificationsconform to IEC 60 298.

Switchgear according to ANSI

The NXAIR P switchgear isalso available as ANSI versionaccording to the followingANSI standards:

Type of service location

• Outside lockable electricalservice locations at placeswhich are not accessible tothe public. Enclosures ofswitchgear can only beremoved with tools.

• Inside lockable electricalservice locations. A lockableelectrical service location isa place outdoors or indoorsthat is reserved exclusivelyfor housing electrical equip-ment and which is kept un-der lock and key. Access isrestricted to authorized per-sonnel and persons whohave been properly instruc-ted in electrical engineering.Untrained or unskilled per-sons may only enter underthe supervision of authorizedpersonnel or properly instruc-ted persons.

Insulating capacity

• The insulating capacity is veri-fied by testing the switchgearwith rated values of short-duration power-frequencywithstand voltage and light-ning impulse withstand volt-age according to IEC 60 694/VDE 0670 Part 1000 (seetable “Insulating capacity”).

• The rated values are referredto sea level and to normalatmospheric conditions(1013 hPa, 20 °C, 11 g/m3

humidity in accordance withIEC 60 071 and VDE 0111).

• The insulating capacitydecreases with increasingaltitude.For site altitudes above1000 m (above sea level)the standards do not provideany guidelines for the insula-tion rating. Instead, specialregulations apply to thesealtitudes.

Site altitude

As the altitude increases, theinsulating capacity of insulationin air decreases due to thedecreasing air density.

For the switchgear thedecreasing insulating capacitymust be taken into accountfor site altitudes above 1000 m(above sea level), see alsoIEC 60 694 /VDE 0670Part 1000.

Result:According to the abovetable, a switchgear for arated voltage of 15 kV isto be selected.
