The Sniffer uses the Wavewin software for data capture, file management, and waveform analysis. Serialports are provided for connecting to and polling other IEDs (refer to the Wavewin Device Managermanual).

SENSORS

A variety of sensors can be used to monitor AC and/or DC Voltages and Currents. The sensors are non-

intrusive which does not require circuit interruption or removing equipment from service. The sensors areconnected to the Sniffer via RJ45 connectors. The RJ45 connectors minimize installation andreplacement time and reduce repair time in case the sensors need to be switched out. The ability toquickly replace sensors simplifies bench testing allowing for the sensors to be replaced in only a fewminutes. Below is a list of available sensors:

EVENT

REPORTS

The Sniffer generates unfiltered events when a trigger is encountered on any of the 24 programmedchannels. Each channel can be programmed to trigger on RMS, Instantaneous, Magnitude or Angle. Thetrigger level is specified by the programming engineer. A digital channel is added when a trigger occurson an analog channel. The digital channel displays the trigger start and end time along with the length ofthe trigger state.

The duration of the event file (in cycles) is also specified by the user. In the Sniffer’s File Properties dialogenter the number of pre-fault and post-fault cycles. Refer to figure 1.5. It is advisable not to exceed 3seconds for a file’s duration (180 cycle’s total). Any file over 3 seconds becomes difficult to analyze. Thedefault values for pre-fault = 6 cycles and post-fault = 54 cycles (saving 1 second files).

The sampling frequency is specified by the user. The default value is 3000 Hz.

A text based SOE report is also generated for each triggered event. The SOE report contains thefollowing fields:

• Trigger Date

• Trigger Time

• Duration of Trigger in milliseconds

• Maximum Value during the Trigger State

• Primary / Secondary Scale

• Primary / Secondary Ratio Order of Trigger


14/86

• Channel Title

• Device Name

• Group Name (Station)

All event files and SOE files are saved in the user defined trigger path. The trigger path is defaulted toc:\Wavewin\Triggers. The Sniffer has a built in processor with 16 Gigabytes of flash drive. The number ofevents stored in the Sniffer is limited to the space available on the 16 Gigabyte flash drive.

System SoftwareThis chapter describes the 2 software applications pre-installed on the Sniffer, the configuration andpolling software (Wavewin Sniffer 24) and the file management and analysis software (Wavewin). The

following sections explain each application.

CONFIGURATION AND POLLING

The configuration and polling software is used to configure the device and for starting and stopping thepolling process. There are 2 main sections, the device configuration and the channel settings. Refer tofigure 4.1.

Figure 4.1 – Configuration and Polling Software

Device Configuration

The 4 fields located in the device configuration section are used to set the general configuration for thedevice. Refer to figure 4.2. Enter the station where the device is located, the name of the device, thecompany that owns the device and the time code where the device is located. When entering informationinto these 4 fields do not include the following characters:

: ? “ / \ < > * | @ #

The peak sample values are displayed in red when the data bar is on the channel’s maximum value anddisplayed in blue when the data bar is on the channel’s minimum value. Use the Tab key to togglebetween the analog and digital channels. To hide the channel information, select the "ChannelInformation" menu option from the "View" menu.

The analog table and combination views can be resized by selecting the vertical separator bar anddragging it to the right or left. The mouse icon changes to the vertical resize cursor when the mouse ispositioned over the separator bar.
