Under voltage is a protective relay normally used in industries for protection of devices when the voltage falls below a certain set value. The relay has a provision to set a threshold voltage and when the voltage falls below this value it trips thereby protecting the system consisting of :-
(1) Input 3 phase DOL Starter panel :
4 pole MCB of 415 V/1A, DOL 9A Contactor with 230V / 50 Hz / 11VA COIL, Bimetallic thermal O/L relay
with range 1.4A Ã¢€“ 2.3A .
(2) Bi-directional 3 phase AC measurement panel
Digital meter (96X96) mm should able to measure following 3ÃŽ¦ & 1ÃŽ¦ parameters, Voltage-line to line & line to neutral, current: for all 3ÃŽ¦ upto 5A, Power factor (0.2 lag-unityÃ¢€“0.2 lead), Frequency, watt, VAR, VA and energy in KWhrs.
(3) FWD-OFF-REV panel will have:
FWD/REV, 3 pole 3 way switch with centre OFF, 6A/440V.
(4) 3-phase Dimmer panel
Table top 3ÃŽ¦ phase dimmer panel should be provided with rating of 415VAC/1A
(5) Single Phasing panel
Consists of three single-phase (SP) fault switches (DPST) one for each phase. Three numbers of bulbs (15W) internally Star connected to indicate SP fault.
(6) Phase sequence indicator and study Expt. Panel will consists of :
(1) Study 3 phase 440V Electric utility supply,
(2) Determination of over voltage, under voltage, single phasing & reverse phasing / Displays OV, UV, SP, RP on digital display,
(3) 9 V Battery / +12V Supply operated.
(7) Protective relay panel will consists of :
Microprocessor based numerical relay with following specs:
(1) Over/Under voltage protection,
(2) Single phase protection,
(3) Reverse phase protection.All the connections of relay should brought out on shrouded socket for easy connection
