Универсалната релейна защита за ел. мрежи и фотоволтаични системи

The Ex9JP F-1 is a specialized Frequency Monitoring Relay designed for monitoring AC frequencies in critical applications such as photovoltaic stations and generators. It supports 50/60/400 Hz frequencies and allows adjustable frequency thresholds (80–120% of nominal frequency), providing adaptability for diff erent power systems. Key features include adjustable diff erence (0.5–5% of Fn) and delay levels (0.5–10 seconds), enabling precise control over frequency variations. The device operates within a 161-500 V AC voltage range and includes 2 change-over contacts, off ering fl exibility in connections. Its user-friendly design, with front-panel switches for settings adjustments, makes it suitable for complex power monitoring tasks.

Ex9JP-G uzraudzības relejs galvenokārt tiek izmantots saules paneļu instalācijās tīklam pieslēgto ķēžu uzraudzībai un aizsardzībai. Tas nodrošina aizsardzību pret pārspriegumu, sprieguma pazemināšanos, fāžu nelīdzsvarotību, fāžu secību un fāžu kļūmēm, analizējot spriegumu katrā fāzē. Piedāvā dažādas aizsardzības funkcijas ar regulējamām vērtībām, piemērojot konkrētās valsts standartiem vai pielāgotai konfigurācijai.
