Metering Description Metering fonctions The values are displayed as primary values with the related units: A,V,Hz,°C,°F, W, … Current # RMS current for each of the 3 phases in the circuit, taking into account harmonics up to number 17 # residual current. Average current and peak demand current # average current on each of the 3 phases # greatest average current on each of the 3 phases (peak demand current). The peak demand currents give the current consumed at the time of peak loads. The average current is calculated over a period that may be parameterized from 5 to 60 mn, and may be reset to zero. Voltage # phase-to-neutral voltages V1, V2, V3 # phase-to-phase voltages U21, U32, U13 # positive sequence voltage Vd # residual voltage Vo # negative sequence voltage Vi. Frequency Power Active, reactive and apparent power, power factor (p.f.). Peak demand power Greatest value of active and reactive power absorbed, over the same period as peak demand currents, with the possibility of resetting to zero. Energy Active and reactive energy. A counter for each current flow direction. Temperature Measurement of the temperature of each sensor. Network diagnosis assistance functions Tripping current Storage of the 3 phase currents and earth current at the time Sepam gave the last tripping order, so as to find the fault current (fault analysis). The values are stored until the next trip order is given. Tripping context Storage of the tripping currents and the Io, U21, U32, U13, Vo, Vi, Vd, F, P, Q, values at the time of the detection of the fault. The values for the last five trips are stored. Negative sequence / unbalance Ratio of negative sequence phase current, characteristic of unbalanced power supply of the equipment to be protected. Phase angles # phase angle ϕ1, ϕ2, ϕ3 between phase currents l1, l2, l3 and voltages U32, U13, U21 respectively # phaseangle ϕo between residual current and residual voltage. Distrubance recording Recording of sampled values of analog measurement signals and logic states. Through parameter setting, it is possible to choose: # the events that will trigger a record # the recording time prior to the occurrence of the event # the number and duration of records (series 40 only). Characteristics Series 20 Series 40 Number of records in 2 Adjustable from 1 to 10 COMTRADE format Total duration of a record 86 periods (1.72 s at 50 Hz , 1.43 s at 60 Hz) Number of points per cycle 12 12 Duration of recording before the occurrence of the event Recorded data Adjustable from 0 to 85 periods Currents or voltages, logic inputs, pick-up Adjustable from 1 s to 10 s The total of all the records plus one must not be more than 20 s at 50 Hz and 16 s at 60 Hz Adjustable from 0 to 99 periods Currents and voltages, logic inputs, pick-up, logic outputs (O1 to O4) Machine operation assistance functions Thermal capacity used Temperature build-up related to the load. It is displayed as a percentage of the nominal machine temperature. Remaining operating time before overload tripping Indicates the time remaining before tripping by the thermal overload protection function. Waiting time after overload tripping Indicates the time remaining before starting is allowed according to inhibition by the thermal protection function. Starting current and time / motor overload Measurement of the maximum current consumed by the motor during a starting sequence or an overload, as well as the duration. Start inhibit time delay / number of starts before inhibition Indicates the remaining number of starts allowed by the starts per hour protection function and, if the number is zero, the waiting time before starting is allowed. Running hours counter / operating time Cumulative time during which the protected equipment (motor or transformer) is on load (I > 0.1 Ib). The cumulative value is displayed in hours (0 to 65535 h). Switchgear diagnosis assistance functions These measurements are to be compared with the data supplied by the switchgear manufacturer. Cumulative breaking current The value displayed may be used to evaluate the state of the circuit breaker poles. Number of operations Total number of opening operations performed by the device. Device operating time Operating time, charging time. These data may be used to evaluate the state of the pole operating mechanism. 10 Schneider Electric
