Energy Metering & Relay Solutions for Railways
As a trusted partner, Blue Jay has supported railway‑industry customers for over 10 years. Work with Blue Jay to ensure continuous operations in Rail transports.
Discover Our Products for Railway
The Railway Electrical Power System consists of the Traction Power Supply System and Distribution Substations to deliver grid power, which directly powers the Railway Rolling Stock and powers the critical Signalling and Control Systems.
We offer energy metering and protection solutions across the entire railway network—from rolling stock to infrastructure and signaling. By continuously monitoring railway electrical systems, we help predict potential faults and reduce downtime, ensuring safe and efficient network operations.
Railway Energy Meter
Railway energy measurement covers total train usage and subsystems including traction drives, HVAC and rheostatic brakes.
Substation‑side metering cannot get per‑train data for efficiency benchmarking. Onboard meters capture bidirectional energy between rolling stock and catenary for accurate consumption and power‑quality monitoring.
Blue Jay supplies AC/DC railway meters and voltage‑current sensors. Our solutions support real‑time energy tracking, train‑line efficiency analysis and cost reduction, compatible with various train models and railway projects.
Insulation Monitoring for Railway
Railway IMDs serve onboard equipment (traction batteries, converters, isolated auxiliary power) and wayside assets (switch heaters, signal houses, traction substations, crossing safety networks).
Blue Jay IMDs work for mixed AC‑DC IT‑type isolated systems. They give early insulation‑degradation alarms, locate faults power‑free, and support remote monitoring & trend‑driven predictive maintenance. The devices cut unplanned outages and on‑site service costs, protect traction/signaling hardware, remove dangerous touch voltages, and safeguard rolling stock, wayside infrastructure and personnel.
Earth Leakage Protection for Railway
Ground‑fault monitoring solutions serve both onboard rail vehicles and track‑side railway signaling infrastructure.
Blue Jay railway‑grade ground‑fault monitoring solutions support both grounded and ungrounded AC/DC power and control circuits to reliably detect and locate ground faults within power‑conversion and railway control equipment, enhancing railway power‑system reliability and safety.
Our Solutions for Different Railway Applications
Trusted by railway operators worldwide, our solutions are built to strict industry standards, delivering exceptional durability and long-term field reliability.
