Page 119: Triggers And Event Recording
Chapter 7 Triggers and Event Recording Introduction Triggering is very useful for testing and troubleshooting electrical power systems. During the occurrence of an electrical event, the 933A can begin recording essential data for analysis. In this section we will look at how the Model 933A uses triggers to record data, and how to conﬁgure these triggers from both the 933A front panel and from PSCSV.
Page 120: Setup
7.1.2 User Triggers User triggers are general purpose in nature (compared to power quality triggers) and allow more ﬂexibility. When active, a trigger signals the Model 933A to record data based on measured parameters, which are then processed by the Model 933A DSP. There are a total of 32 diﬀerent triggers available that you can assign as either a User or Power Quality trigger.

For example, if due to usage requirements the line voltage sags during the day and swells during the night, you might want to use a sliding reference to avoid unnecessary triggers.
Page 130: Event Waveform Capture
Remember that if you have several triggers armed, any of them may be responsible for the 933A logging data if they become active. Event Waveform Capture 7.4.1 Capture Method and Features The Model 933A samples each of the six measurement channels at 10,240 samples per second at 16 bit resolution, and begins sampling when triggered from a speciﬁed event.
Page 131: How Much Data Do I Record
7.4.3 How Much Data do I Record? It takes about 18 minutes to ﬁll up 128 MB of waveform ﬂash with the six input channels - three voltages and three currents. Decide how much waveform data you really need to record following an event. A few seconds of data is should be ample for each record, however the 128 MB allows for additional event recordings, providing the postfault data is kept short.
Page 132 Note: The 933A records complete sets of one-second data around the occurrence of the event, depending on the set Logging Times. The 933A stores the main data records in the standard ﬂash module, and stores high- speed waveform in another 128 MB ﬂash module used exclusively for that purpose.

Proprietary technology developed by Arbiter Systems and reﬁned in several generations of GPS timing products also help to achieve accuracy. By comparing the internal 10-MHz crystal oscillator to the 1 PPS from an IRIG input or the output of a GPS receiver, the 933A can maintain its frequency at any time within a few parts in 10 and time within one microsecond.
Page 149: Error Analysis
Error Analysis All identiﬁed sources of error in the 933A have been quantiﬁed using worst- case manufacturers’ performance data. These have then been combined using a root-sum-of-squares (RSS) method to yield a performance estimate. Eﬀects due to initial calibration, measurement noise, temperature, and aging are all included.
Page 150: Signal Sampling
Signal Sampling Each of the signals, representing the scaled voltage and current inputs have their own ADC. Each signal is sampled simultaneously at a rate of 10,240 samples per second. If connected to an external timing source (e.g. GPS) it provides the sample clock to the 933A, it is synchronized to UTC-USNO (GPS), allowing measurements of phase angle across a power grid to be compared directly.

Voltage and Current Voltage and current are measured in a similar fashion to power, using overlapping 1024-point measurements. In this case, however, the cross product is replaced with the square of the voltage or current samples.
Page 152: Transformer Compensation
9.11 Transformer Compensation There are two diﬀerent types of transformer compensation. They are used to correct for the losses in a transformer when primary-side metering is used to meter the energy delivered to a customer at the secondary of the transformer.
Page 153: Phase And Frequency
9.13 Phase and Frequency As a part of its measurement process, the 933A performs a fast Fourier transform (FFT) of the windowed voltage and current samples. accordance with IEC 61000-4-7, this process is performed twenty times per second, using overlapping 1024-sample Hanning window data. This yields new FFT results twenty times per second for each voltage and current input, for a total of 120 FFT’s per second.

taking the arctangent of the real and imaginary components of the bin closest to each harmonic. This information cannot be used, however, in the averaging process described in IEC 61000-4-7, because this speciﬁcation requires the rms average of a series of measurements. This, by deﬁnition, requires magnitude data only.
