Measuring Relays for the Rail Industry

Electromagnetic Relays for Trackside, Signalling and Rolling Stock Applications

TECHNO-ELEC specialises in designing, manufacturing and selling measuring relays, known as ‘responsive relays’.

TECHNO-ELEC is a key partner for electrical traction systems (metros, tramways, trains, high-speed trains, substations).

Our areas of expertise are in on-board and trackside railway applications.

Our Services

Studies

  • Designing and manufacturing relays, specifically: voltage relays, current relays, differential relays or custom relays for a specific application, based on Servo-Contact technology
  • Consulting and advising on a choice of features such as size the product according to customer needs

Production & Marketing

  • Development, manufacture and sale

Aftersales Service

  • Preventive maintenance (product functional checks)
  • Corrective maintenance (expertise and repair, provision of replacement parts change of wear parts)
  • Specific maintenance contracts

Main Characteristics

  • Operation fields: from 1mA to 15,000A / from 10mV to 4,000V (AC/DC)
  • Dielectric strength: up to 20,000V 50Hz- 1 min (primary circuit/secondary circuit)
  • High overloads on measuring circuits
  • Fire resistance according to standards NF F16-101-102 & EN 45545
  • Fully operational, whatever the direction

Categories of Relays

Current Relays

Current relays are used in applications such as current detection, threshold control, overload detection, ground fault detection, engine start, etc.

For trackside installations, ground fault detection relays measure the DC current from the frame to the ground. Mainly installed in Metro and Tram DC substations, the relay is connected between the ground and the cubicle frame. In the event of an isolation failure, the fault current flows through the relay that picks it up. No auxiliary power is required.

Voltage Relays

Voltage relays are used in applications such as voltage detection, catenary voltage detection, threshold control, voltage monitoring of battery chargers, etc.

In trackside installations, for DC traction networks (750, 1500 and 3000 VDC), catenary voltage relay is used to detect the presence of voltage in the cells from the rectifier. The high insulation resistance (up to 12 kV under 50 Hz) offers a high resistance to overvoltage, especially natural phenomena (e.g. lightning). In addition, no auxiliary power is required.

Differential Relays

Differential relays are used in applications such as DC or AC current differential protection, AC or DC voltage differential protection, etc.

Custom Relays

Custom relays, associated with electronics, allow customers to benefit from more specific relays, such as time relays on closing or tripping, flashing relays, clipper time relays, etc.
