Buswire Supervision Relay

​

Used to ensure the integrity of busbars and restricted earth fault schemes, the MVTP monitoring device has a low AC burden and requires no external resistors.

​

Single and 3-phase for continuous buswire supervision

​

Available in single and 3-phase relays, the MVTP provides continuous supervision of the buswires in high impedance type busbar protection schemes. It also detects open-circuited buswires as well as open-circuited main current transformers.

​

Integral buswire shorting facility

​

MVTP is equipped with an integral buswire shorting facility. With low AC burden capacity, MVTP requires no external resistors. It also ensures that MCAG and MFAC schemes are available.
