JVS Electronics offers under/over frequency relay of type – JRF 014.
Product & Technology News
- Two stage of frequency protection digital display of line frequency draw out case 144x144 mm
- The relay provides time graded over/under frequency protection; used in industrial plants having captive power generators requiring under frequency protection
- The relay JRF 014, is a microprocessor based frequency relay; it can be configured for 2 stage under frequency relay, two stage over frequency relay or Under/over frequency relay
- The relay's operating time can be programmed; the relay measures line frequency and if it exceeds the set threshold in case of over frequency or if it is less than set threshold then relay extends a trip signal after an operating time
- Accuracy: frequency measurement: ±0.0 l Hz; operating time: ±2% or ±50ms whichever high.
