Ashida electronics pvt. Ltd. One of the leading designers, developer & manufacturers of electrical power protection relays, scada systems & metal detector offers wide range of protection relays. These are dsp based `numerical` communicable/non-communicable non-directional oc/ef relays. These are available with number of protection functions such as lbb, trip circuit supervision ,di/do etc
The adr241b is plan to convene the order of low and medium switchgear control. The adr241b is a 3 oc and 1 ef relay with instantaneous high set and programmable output to simplify feeder protection wiring. The adr241b continuously monitors all 3 phase and earth current, through ct connections. The high-speed micro-controller samples this current through a 12-bit a/d converter and metering function. All measurement is tuned to fundamental frequency. Each input current is also displayed on 16 x 2 lcd
