Dold mittausreleet verkon valvontaan
Verkonvalvontareleet valvovat yli- ja alijännitettä, jännitealueita, vaihesymmetriaa ja vaihejärjestystä. Mittaustoiminnot ovat helposti säädettävissä releen etuosan kiertokytkimillä.
Verkonvalvontareleitä voidaan käyttää valvomaan esimerkiksi koneiden, voimalaitosten, ohjausjärjestelmien ja rakennusten vaiheverkkoja.
Tärkeimmän ominaisuudet:
• Monipuolinen valikoima valvonta- ja mittausreleitä
• Ennakoiva vaihehäiriöiden havaitseminen järjestelmän käytön aikana
• Useiden eri mittausarvojen tarkka valvonta
• Laajat mittausalueet
• Ei tarvetta erilliselle apujännitteelle
• Toiminnot helposti valittavissa kiertokytkimillä
• Saatavana UL-hyväksynnällä
