| 1 | (A) At Raw Water (Intake Well) P/P, Bheri Farm :-Providing, erecting 200 KVA Servo Controlled Automatic Voltage stabiliser suitable for out put voltage of 415 Volt +/-1%, Input 240 to 460 Volt . 3 Ph, 50 Hz, with copper wound transformer (air/oil cooled) as mentioned below. The stabilizer shall function satisfactorily even if incoming supply is unbalanced between phases within range of 10%. The stabilizer should be constructed in cubical box, with bidirectional wheels for easy handling, necessary monitors and user's controls on front panel such as indication, alarm, volt meter and selector switch for measuring input and out put voltage, Auto/Manual selector switch, Raise/Low push buttons etc. Suitable capacity termination strips and bus bars for incoming and out going cables, earthing with change over switch should be provided. All three phases shall be independently monitored and corrected. Following protections and indications shall be incorporated.1.Over Voltage / Under Voltage,2.Single Phasing,3.Cut off contactor with electronic output sensing unit.Make –Sen & Pandit/Revolt Power/Numeric/PVJ Power/PACT/Power Star |
| 2 | Supply Installation and Commissioning of 200 Amp. 4 Pole on/off load Change over switch in sheet enclosure with side handle operation for making Bypass System. Make Havells / HPL / C&S. |
| 3 | Cost towards supply and First filling of transformer oil. |
| 4 | Cost towards Supplying and laying 150 sq. mm x 3.5 core PVC sheathed & PVC insulated, 1.1 KV grade aluminium armored cable. Make – Polycab/ KEI/ Universal/ISI |
| 5 | Cost towards supply and making arrangements for chemical earthing as per I.E. rules. |
| 6 | Cost towards making earthing connection from earth pit to panel, starter & motor etc. with 6 SWG G.I. wire. |
| 7 | (B) At WTP P/p, Chatra :-Providing, erecting 300 KVA Servo Controlled Automatic Voltage stabiliser suitable for output voltage of 415 Volt +/-1%, Input 240 to 460 Volt .3 Ph, 50 Hz, with copper wound transformer (air/oil cooled) as mentioned below. The stabilizer shall function satisfactorily even if incoming supply is unbalanced between phases within range of 10%. The stabilizer should be constructed in cubical box, with bidirectional wheels for easy handling, necessary monitors and user's controls on front panel such as indication, alarm, volt meter and selector switch for measuring input and output voltage, Auto/Manual selector switch, Raise/Low push buttons etc. Suitable capacity termination strips and bus bars for incoming and outgoing cables, earthing with changeover switch should be provided. All three phases shall be independently monitored and corrected. Following protections and indications shall be incorporated. 1. Over Voltage / Under Voltage, 2. Single Phasing, 3. Cut off contactor with electronic output sensing unit. Make – Sen & Pandit/Revolt Power/Numeric/PVJ Power/PACT/Power Star |
| 8 | Supply Installation and Commissioning of 315 Amp. 4 Pole on/off load Change over switch in sheet enclosure with side handle operation for making Bypass System. Make Havells / HPL / C&S. |
| 9 | Cost towards supply and First filling of transformer oil. |
| 10 | Cost towards Supplying and laying 185 sq. mm x 3.5 core PVC sheathed & PVC insulated, 1.1 KV grade aluminium armored cable. Make – Polycab/ KEI/ Universal/ISI |
