Mode Operation
1822 suitable controlling 3-phased motors generators. relay measures effective power: measuring phase voltage through pins phase sequence arbitrary. current measured phase current metering transformer type increased sensitivity required, metered cable through current transformer several times. 1822 measures power phase; symmetrical loads this phase representative phases. When registered effective power exceeds power limits, relay operates with delay sec. relay releases immediately when measured effective power drops below value less hysteresis. measured effective power read connected instrument. wrong direction, instrument displays zero. detection direction time constant, relays also suitable connection with decoupling windmill generators. relay also suitable where reading instrument well monitoring consumed power required. 1822 applicable controlling mechanical loads because takes into consideration changes current well Note: Internal measuring circuit connected pins pins except relay contacts have potential power supply, this applies instrument well.
