  • The synchro-check relay can be used to assist in the semi-automatic parallelling of two AC power systems . The volt-free relay contacts change state when the voltage level, phase relationship and frequency are within the selected synchronising limits . Connecting two electrical systems that are not closely matched can cause expensive damage and disturbance to the electrical system. Using this relay will ensure that damage will not occur . Other features of this device are : - Single phase or three phase, 3 or 4 wire - Live and dead bus versions - Adjustable setpoint - LED trip indication - Volt free relay contacts Bornika is the exclusive agent of Ziegler company in the fields of consultation , sales and distribution of power industry products including Synchro-Check (parallelling) Relay .

More details
  • Synchro-Check (parallelling) Relay:
  • 256-PLL : The relay continuously monitors the voltage, phase displacement and frequency of two supplies. A single setpoint adjustment permits selection of suitable matching , and a red LED illuminates when the relay is energised , indicating that the two supplies are well matched and it is safe to close the breaker. 256-PLD : This version operates in the same way as model 256-PLL , but includes an additional dead bus detection function. If there is a requirement for a continuous supply or emergency power, then the generator can be connected without synchronising, thus ensuring continuity of supply . The absence of bus voltage will cause the relay to energise . - Operating temperature : 0°Cto +60°C - Material : Flame retardant polycarbonate/ABS - Enclosure style : DIN-rail with wall mounting facility Applications : Marine panels , Switchgear , Distribution systems , Generator sets , Co-generation , Control panels
