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 adr141a is design to meet the demand of low and medium switchgear control. The adr141a is a 3 oc and 1 ef relay with instantaneous high set and programmable output to simplify feeder protection wiring. The adr141a 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. The adr141a give maximum benefit/cost ratio. The adr141a give all the advantage of numerical relay at affordable cost. The adr141a has 4 sensing element 3 oc and 1 ef. The adr141a provide separate programmable alarm contact.
