Amount

Design, Fabrication,Installation, Testing and Commissioning Of Automation System For Operation and Regulating 12 No of Tubewell i. e ( T/W Balwan Singh, T/W Chack manga Gujran, T/W Labh Singh, T/W Kali bari, T/W Manohar Goaplla, T/W Madhera, T/W Parel, T/W No 1, T/W chatte vala khoo, T/W NO 5, T/W Sonarki and T/W Filteration Plant)by using GSM of suitable capacity rating as well as fault analyser cum protection panel .

1) Fabrication of Power Handling Unit (PHU) / Auto Starter with power contactor MNX-50-3Nos. of L&T make along with MCCB of 100 ampere rating also of L&T make. 2) The system should be provided with a solid state fault analyzer cum controller make. 3) The complete system should be enclosed in a floor / wall mounted MS sheet enclosure / box of suitable gauge and dimensions with proper entry and exit holes for incoming and outgoing Conductors . The enclosure should be finished with powder coated painting from inside as well as from outer surface of approved colour. Job also includes mounting of the panel to the wall / floor of the pump room. 4)The job also involves Laying/ Providing and fitting of PVC Copper cable of suitable rating and length from voltage stabilizer / main switch / motor to the automation –cum protection panel. All the electrical connections should be made after proper thumbing and end socketing of each cable end with copper thumbing of appropriate rating.

Features and Specification 1) The system should trip the motor on power failure and on appearance of an electrical fault mentioned below which may otherwise damage the motor field coils and should not restart automatically unless and until the system is reset manually and sms is generated to control unit thus providing automation to the system and protection to the motor.

2) The system / star delta auto starter should not fall into delta if it does not fall into star mode first and should remain de-energised to avoid damage to the motor / machinery and also to the power source / transformer.

3) The system / star delta auto starter should trip off if it does not fall into delta & remains in star mode for more than 10-20 seconds.

1) The system shall provide protection against:-

a. Low voltage below 350 V

b. High Voltage above 450 V

c. Single phasing

d. Reverse phasing

e. Un Balanced phasing

GSM Mobile Operation:- Designing, providing, installation, testing and commissioning of GSM mobile activation and deactivation switch for pumping machinery through LT control panel. The job includes installation of automation device inside the panel at suitable place. Automation device should be suitable for pumping machinery i.e. submersible pump set through mobile app from anywhere.

It shall be equipped with following features: - i) Device shall have provision for insertion of SIM of any network provider. ii) Device shall be able to register minimum 3 numbers for operation. iii) Device shall be operated from mobile and shall respond to a call and a sms from the registered mobile numbers for machinery operation i.e. ON and OFF from mobile by call and sms mode. iv) Device shall be able to deliver present status of the pumping machinery that is ON/OFF.

Complete job includes cost of panel/ material, labour charges, transportation/ shifting charges up to site of work, including installation, testing and commissioning.
