17. APPENDICES

This chapter presents the mathematical formulae used for calculating different parameters for C.A.8335.

17.1 Mathematical formulae

17.1.1 Network frequency and sample

The sample is applied to the network frequency to obtain 256 samples per period of 40Hz to 70Hz. Feedback is essential for calculating reactive power, imbalance and harmonic rates and angles.

Frequency measurement is determined by analysing seven passes by zero positive and consecutive on the first voltage channel (V1) or the first current channel (I1) after digital low-pass filtering and deletion of the continuous component.

The precise temporal measurement of the zero pass point is achieved by linear interpolation between two samples to achieve better solution than 0.002%.

Signals are acquired with a 16 bit converter and (in the event of current acquisition) dynamic gain switches.

17.1.8 Harmonic calculations (ex neutral)

These calculations are carried out by FFT (16 bits) 1024 points, in four periods without windowing (see CEI 1000-4-7). Using real parts bk and imaginary parts ak, the rate is calculated for each rank and each phase (Vharm[3][51], Uharm[3][51] and Aharm[3][51]) in relation to the fundamental value and the angles Vph[3][51], Uph[3][51] and Aph[3][51] in relation to the fundamental.

This calculation is carried out according to the following principle:

17.2 Hysteresis

Hysteresis is a principle of filtration that is often used after a threshold detection stage in Alarm mode (See para 4.10 page 15). Correct regulation of the hysteresis value avoids repeated status changes when the measurement oscillates around the threshold.

17.2.1 Surge detection

For a hysteresis of 2%, for example, the level of return for surge detection is equal to (100 %-2 %) or 98 % of the reference voltage threshold.

17.2.2 Detection of under-voltage or interruption

For a hysteresis of 2%, for example, the level of return in the event of under-voltage detection is equal to (100 %+2 %) or 102 % of the Uref voltage threshold.

17.5 Mechanism for triggering transient sensors

The sample rate is a constant value equivalent to 256 samples per cycle. When a transient search is launched, each sample is compared to the sample from the preceding cycle. The preceding cycle matches the middle of the tube; it is used as a reference. As soon as a sample leaves the tube, the trigger event comes; representation of the transient is then captured by the C.A. 8335. The cycle preceding the event and the three following cycles are saved to memory.

Here is a graphical representation of the transient capture trigger mechanism:

Here are the tube half-widths for voltage by type of sensor:

17.6 Sensor conditions in Ringing Current mode.

Reminder: Sensors depend on the trigger event and a stop event. If capture ends with a stop event or if the save memory of the C.A. 8335 is full, capture stops automatically.

The stop threshold for capture is calculated as follows:

[End threshold [A]] = [Start threshold [A]] × (100 – [End hysteresis [%]]) ÷ 100

Here are the conditions for triggering and stopping capture:

Triggering filter type Start and end conditions

A1 Start condition [A1 half-period RMS value] > [Start threshold] End condition [A1 half-period RMS value] < [End threshold]



3A Start condition [the half-period RMS value of one current channel] > [Start threshold] End condition [the half-period RMS values of all current channels] < [End threshold]

17.7 Glossary

Ampere : unit of electrical current intensity (A symbole).

Bandwidth: frequency range on which an instrument supplies a precise measurement.

Fundamental component : component whose frequency is the fundamental frequency.

Cut: reduction in voltage at a point in the electrical power network below the cut threshold.

Voltage dip: temporary reduction in the voltage amplitude at a point in the electrical power network below a given threshold.

Peak factor relation between the peak value and efficient value of the current.

Phase displacement factor: relationship between the active power and apparent power of the fundamental component.

Power displacement factor: expresses the difference between the apparent and active power when and only when the relationshop of the voltage phase and current to the fundamental is taken into account.

Factor K number based on the contents of a harmonic of a charge current that determines the maximum load on a source of energy. The K factor calculated by the C.A. 8335 is measured and compared with the one specified by the transformer manufacturer. It gives the percentage of “harmonics load” of the transformer.

PST : (Short term perception). Calculation of flicker over a ten minute cycle.

PLT : (Long term perception). Calculation of flicker over a two-hour cycle.

Harmonics level whole number equal to the relationship between the frequency of the harmonic and the fundamental frequency.

RMS : Root Mean Square. Efficient value of a current or voltage.

Dip threshold: specific voltage value to detect the start and end of a voltage dip.

Temporary surge at industrial frequency: temporary increase in the voltage amplitude at a point in the electrical power network above a given threshold.

Nominal voltage: voltage by which a network is named or identified.

THD: Total Harmonic Distortion. Total harmonic distortion. The rate of total harmonic distrotion gives the influence of harmonic components in a signal.

RMS value square root of the average squares of values for a specified interval.

Measurement method: all measurement methods associated to an individual measurement.

Phase and route: a measurement route corresponds to a difference in potential between two conductors. A phase is a simple conductor. In polyphased systems, a measurement route can be between two phases or a phase and neutral or a phase and earth or neutral and earth.

Watt : unit of measurement for power (W symbol).
