−
Fuse failure detector in voltage measuring circuits.
−
Remote open detector (without communications channel). (MLP3000)
−
Fault selector
−
Fault locator (MLP 3000).
−
Oscillographic register that retrieves seven fault situations, which are stored for
at least two hours in the event of a power loss. (MLP4000)
The oscillographic register retrieves data such as the waves of the three currents
and voltages, status of the inputs and outputs, distance protection signals, reclosing
signals and blocking signals. The register capacity is 30 cycles: two prefault cycles and 28
postfault cycles. The information generated by the fault selector (type of fault and it's
location) and the type of trip performed will be stored. Data can be retrieved and saved in
an ASCII file.
The MLP system protection and resetting operations are independent from control
and communications operations so that a highly reliable protection operation can be
ensured even in the case the rest of the components failed.
The MLP is stored in a unique assembling case 19". Dimensions are provided in
figure 2.
It also includes an internal clock (without battery) with hundredths of a second
precision. As it does not have a battery, it is necessary to set the time of relay when it is
put into operation. In the event of a power loss, the clock will maintain date and time for
two days.
