Western Railway Transformer Turns Ratio Test Set Tender 240V 50Hz ISO Standards 2025

Tender Overview

The Western Railway division of Indian Railways invites bids for a Transformer Turns Ratio Test Set (BHEL) to support on-site testing of three-phase transformers. The scope includes supply, installation, testing, commissioning, operator training, and any required statutory clearances. The technical terms mandate a 240 Volt, 50 Hz operation and an AC 240 Volt test voltage with accurate turns ratio measurement across different vector groups without phase conversion. The contract supports quantity adjustments up to 25% during and after award, with delivery timing linked to the original delivery period and extended time rules. The procurement emphasizes local supplier eligibility under MSE preferences and requires compliance with center-purchasing policies where applicable. The absence of a BOQ implies a compact but high-precision electrical test instrument with strict performance and compliance expectations.
