Mounting & Wiring
Features:
- Integral buswire shorting facility
- Low AC burden
- No external resistors required
- Hand-reset mechanical flag
- Self-monitoring capability
- Continuous AC voltage input monitoring
- Type MVTP 31 - three phase relay
The AC voltage input is continuously monitored and when it exceeds the level pre-set by means of the plug setting, the output relay is actuated after a three or ten second delay.
The hand reset contacts of the output relay are normally connected across the buswires of the busbar protection thus short-circuiting the busbar protection relay and rendering the protection of the zone concerned inoperative.
The MVTP31V1CB0751E ALSTOM BUSWIRE SUPERVISION RELAY may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The AC voltage input is continuously monitored; when the input voltage exceeds the preset value on the plug, the output relay will activate after a 3-second or 10-second delay.
The manual reset contact of the output relay is typically connected to the busbar of the bus protection device, thereby short-circuiting the busbar protection relay,and disabling protection in the affected area.
A manual reset contact for alarm purposes is also provided on the same output relay.
The relay's operating status is indicated by a manual reset mechanical indicator.
- Power Generators: Monitors restricted earth fault (REF) for large generators.
- Industrial Motors:Protects high-capacity motors by rapidly clearing high-magnitude fault currents.
- Traction Transformers: Monitors power systems feeding locomotives and regional trains.
- Point Machines:Integrated into wayside systems controlling track switching.
- Track Circuits & Detection Devices:Supports fail-safe axle counters & track occupancy detection.

Orientation: Mount the relay vertically on a standard 19-inch rack or a dedicated protection panel.
Terminal Connections: Wire the main Current Transformer (CT) secondary leads to the relay's high-impedance buswires.
Shorting Contacts: Ensure the buswire shorting contacts are wired to the main protection relay’s "block" or "inhibit" input. If the MVTP detects a fault in the wiring, it must "freeze" the protection to prevent a false trip.
FAQs
-
What is the primary function of the MVTP relay?
+It provides continuous monitoring of buswires in high-impedance busbar protection systems to detect open-circuit conditions of either the buswires or the main current transformers -
What happens when a fault is detected?
+If the monitored voltage exceeds the preset level, the output relay activates after a set time delay (typically 3 or 10 seconds) to provide an alarm and/or take the faulted protection zone out of service. -
What is the setting range of the MVTP31V1CB0751E?
+The relay has a setting range of 1-16 V, which is adjusted using DIL switches located on the front panel. -
What is the trip delay of the MVTP31V1CB0751E?
+When the AC input voltage exceeds the preset value, the output relay will operate after a delay of three or ten seconds. -
What is the maximum rating of the MVTP31V1CB0751E?
+Its rated continuous voltage is 600 V rms, and standard operation requires no external components.
