All metering functions shall meet the required industrial accuracy, stability, and interoperability norms- 180 Nos Complete all as specified and as directed by engr-in-charge.

Supply, Installation, testing and commissioning of LT Current Transformers shall be suitable for use on a 1.1 kV, 50 Hz system and may be supplied in resin-cast or moulded construction, ring type or bar-primary as required. CTs should generally follow accuracy class 0.5 for metering, with a typical burden around 10 VA and secondary rating of 5 A (or 1 A if specified). Primary ratios shall be provided as per the load requirement. The CTs should comply with the relevant IS/IEC standards for LT metering-grade transformers and withstand normal insulation and thermal conditions for LT panels. They should be suitable for busbar or panel mounting and marked with basic details such as ratio, class, burden, and manufacturer information. Complete all as specified and as directed by engr-in-charge. 540 Nos

Supply, Installation, testing and commissioning firewall for VPN termination - 01 No. The bidder shall deploy an advanced perimeter isolation mechanism capable of enforcing segmented trust boundaries within the proposed private communication fabric. The firewall system shall operate in a mode that ensures that all operational traffic traverses through controlled inspection zones, with routing decisions governed exclusively by predefined trust policies rather than public-network reachability.the firewall enforces persistent state validation, controlled service exposure, and complete suppression of unintended ingress or egress pathways. The system must maintain operational continuity under fluctuating network conditions and support transparent integration with the underlying non-public transport infrastructure used for data acquisition. Complete all as specified and as directed by engr-in-charge.

The bidder shall establish a secure, private communication framework enabling controlled acquisition of operational data between remote field locations and the central supervisory environment. The solution shall utilise carrier-provided, non-public wide-area transport mechanisms based on dedicated OT-grade cellular or equivalent isolated network technologies. The communication path shall remain logically segregated from any public Internet infrastructure, ensuring deterministic routing, controlled access domains, and end-to-end confidentiality of all telemetry exchanges. The bidder shall also ensure that the private WAN construct incorporates resilience measures to maintain uninterrupted data flow to the designated head-end systems. Complete all as specified and as directed by engr-in-charge.

The bidder shall provide an industrial-grade 5-port unmanaged Ethernet switch suitable for reliable data exchange within the proposed closed communication environment. The switch shall offer auto-negotiating Ethernet interfaces supporting standard data rates, with non-blocking internal switching capability to ensure uninterrupted packet flow. The device shall operate without configuration requirements and shall provide transparent forwarding across all ports. It shall be equipped with appropriate electrical and environmental endurance to function in typical industrial panel conditions and shall support stable operation under continuous service. The switch shall include provisions for basic protection features inherent to unmanaged devices and shall integrate seamlessly within the private OT communication framework. Complete all as specified and as directed by engr-in-charge.

Supply, Installation, testing and commissioning of Server PC shall be a workstation-class system suitable for running medium-to-high processing applications with reliable 24×7 operation. The unit shall be equipped with a multi-core processor of contemporary generation, providing adequate capability for application hosting, background services, and data handling tasks.
