More Information

Overview Manuals Monitoring Timing Contacts Application
  • Continuously supervises buswires in high-impedance protection schemes.
  • Detects open-circuited buswires and open-circuited main current transformers.
  • Provides integral buswire shorting, alarm contacts and a mechanical operation flag.

MVTP31V1CB0751E is an Alstom buswire voltage supervision relay designed for its documented industrial platform or application.

The supplied AREVA T&D Automation nameplate confirms Cortec Code MVTP31V1CB0751E. The current GE Vernova MVTP brochure identifies MVTP31 as the three-phase buswire-supervision version and documents its supervision, timing and contact functions.

Before installation or replacement, verify the complete catalog number, compatible hardware, wiring, configuration and installed-system requirements.

Availability, condition, price, and shipping time for MVTP31V1CB0751E are confirmed during quotation.

  • Continuously monitors the AC voltage input against the selected threshold.
  • Actuates the output relay when the monitored voltage exceeds the preset level.
  • Indicates relay operation with a hand-resettable mechanical flag.
  • Offers a fixed three-second or ten-second operating delay selected when ordering.
  • Specifies a 150 ms contact disengaging time.
  • Specifies a drop-off/pick-up ratio above 85% after the three-second delay and above 98% before it.
  • Uses normally open buswire shorting contacts.
  • Allows alarm contacts to be specified as 2 make, 1 make/1 break or 2 break.
  • Rates the hand-reset contacts to carry 150 A rms for 0.5 seconds.
  • Buswire supervision in high-impedance busbar protection schemes
  • Buswire supervision in restricted earth-fault protection schemes
  • Availability supervision for MCAG and MFAC protection schemes
Description
MVTP31V1CB0751E uses front-panel DIL switches to set its buswire supervision threshold from 1 to 16 V rms in 1 V steps. The selected threshold is monitored across all three phases with a fixed operating delay of either 3 or 10 seconds.

When the monitored voltage exceeds the preset level, the output relay operates after the configured delay. Its hand-reset contacts short the affected protection buswires, separate contacts initiate the alarm, and a mechanical flag retains the operation indication until manually reset.

A replacement MVTP31V1CB0751E must match the installed DC auxiliary voltage, 3-second or 10-second delay and alarm-contact arrangement of 2 make, 1 make and 1 break, or 2 break contacts. Verify these order-specific selections against the relay label and scheme drawings before reconnection.

Technical notes
MVTP31V1CB0751E requires exact-suffix confirmation of auxiliary supply, contact arrangement, case, terminals and protection-setting documentation records before replacement; MVTP31 family data alone cannot establish configuration compatibility.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which ordering-code details must be confirmed before selecting MVTP31V1CB0751E?
Confirm the complete suffix on the nameplate, auxiliary-supply code, contact arrangement, case style and terminal plan because the reviewed official brochure identifies only the MVTP31 family.
Can an MVTP31 relay with a different suffix replace MVTP31V1CB0751E?
No interchangeability is established. Compare the complete ordering code, supply, output contacts, case and terminal allocation before considering any family variant.
How should the supervision threshold for MVTP31V1CB0751E be validated?
Use the exact unit's settings and protection design; the family brochure shows a 1–16 V RMS range, but the complete V1CB0751E configuration remains unverified.
Which wiring documents are required before installing MVTP31V1CB0751E?
Obtain the exact-suffix connection diagram and terminal schedule, then reconcile them with the panel drawing before moving any buswire or alarm circuits.
Are the relay contacts supplied as a separate accessory for MVTP31V1CB0751E?
The family diagram shows integral alarm contacts, but the exact contact arrangement for V1CB0751E must be confirmed from the unit-specific order code and documentation.
What should be checked when MVTP31V1CB0751E does not issue the expected alarm?
Verify auxiliary power, applied supervision voltage, selected setting and alarm-contact wiring against the exact unit diagram; family-only evidence is insufficient for terminal-level assumptions.
What evidence is needed to commission MVTP31V1CB0751E safely?
Require the exact nameplate, terminal diagram, auxiliary-supply rating and setting record, then perform the protection scheme's approved secondary-injection and alarm-contact checks.
