INTERFACE PROTECTION SYSTEM UNIT FOR LOW VOLTAGE

General characteristics

Operational characteristics

PMVF 60 interface protection (IP) system unit has been developed according to the Engineering recommendation SHAMS DUBAI - DRRG (DEWA) - SEC (Saudi Electricity Company) technical standard. Each is used when a local generating system is connected in parallel with the low and medium voltage electric utility. The controls refer to limits of voltage and frequency monitoring.In the case when either the voltage or the frequency are out of admissible limits, the IP must step in by de-energising a relay output so that the interface switch (IS) trips.PMVF 60 is equipped with 4 inputs having the following functions:– IS status feedback– External signal for frequency selection– Disabling signal– Remote tripping (forced IS opening, independent of

voltage and frequency values).Also, there are 2 relay outputs for:– IS opening and closing– Backup device opening (programmable: retentive

normally energised, retentive normally de-energised or adjustable pulse).

The backup device consists of a signal contemporary or with a 0.5s delay respect to the IS opening command, transmitted only if the IS failed and did not complete the disconnection.PMVF 60 also has 2 additional relay outputs to configure as:– Autonomous signalling in case of phase power

unbalance (LSP), only if three CTs are also installed– Programmable alarm.
