Product Details

ELSPEC G4100 Display Unit. The Elspec G4100 Remote Display LCD Unit is an integral part of the Elspec Power Quality Data Center system, allowing interconnectivity with the G4400 series instruments for configuring and monitoring the electrical distribution system. The Elspec G4100 Remote Display Unit (RDU) connects and communicates with the G4400 Power Quality Data Center instrument directly via RJ45 network cable or through IP communication from anywhere in the world. One RDU can be used to monitor and configure many G4400 series instruments. The Elspec G4100 enables configuring all aspects of the G4400 series instruments and displays all monitored real time values. Figure 1 describes the role of the G4100 in managing power quality data in a power distribution system.

The G4400 series Power Quality Data Center instrument is connected to the electrical system via current and potential transformers. These instruments constantly record the voltage and current waveforms at a resolution of up to 1024 samples per cycle. This data is compressed on board using the Elspec patented PQZip technology. The PQZip files are transferred to a PNode running on a server managed by the Site Manager. The PNode stores the data collected from the instrument and responds to requests from client workstations running Elspec Investigator software. When an engineer using the Investigator software wishes to analyze the data collected by the instrument from a certain time frame, the PNode decompresses the requested data, performs the necessary mathematical calculations to display the electrical parameters requested by the client and then arranges and configures the data to be displayed on the specific screen used by the client.

Every G4400 instrument hosts an onboard Website allowing access to data from any web browser. Inputting the IP address of the instrument in the address window of an internet browser will bring the G4400 webpage to the browser with current real time monitored values. Configuration of the G4400 instrument may also be achieved via theWebsite. The Elspec IP Address Search Tool is an important element in the Elspec Power Quality Data Center System. This utility allows all G4400 and G4100 units connected to a LAN to be found and identified on line.

The G4100 Remote Display LCD is used to both configure and monitor the G4400 series instruments achieving much the same effect as when using a web browser but with the added tactile feed back only a dedicated LCD display can offer. The G4100 can be used as a hand held monitoring and configuring tool connecting to each G4400 instrument in turn using an RJ45 network cable, or optionally plugging into a network connection and alternately inputting the IP addresses of the different instruments.

PQA Technology

No Triggers/No Thresholds means no missed events. Optimizing Power Quality Data Analysis Using Patented Data Compression Technology. The main objective of an engineer troubleshooting a power quality event is to identify the source of the disturbance in order to determine the required corrective action. To identify the source, the engineer depends on recorded data captured by monitoring equipment.

The management demands a cost effective method to solve the problem as quick as possible. The electrical engineer speaks of installing instrumentation, collecting data, analyzing data, re-installing and re-analyzing. It is not uncommon for months to pass until the problem is isolated and a solution is implemented.

Power quality analysis has traditionally posed a unique challenge to the engineer, demanding an accurate assumption as to the dimensions of the disturbance in order to capture the event to memory for examination. The correct balance between memory size and the deviation of the disturbance from the norm is often elusive. Thresholds set too low capture too many events of little or no consequence, filling the memory before the sought after damaging event occurs. Setting the threshold too high can overshoot the event.

What is Data Compression Technology?

Revolutionary data compression technology takes the guess-work out of isolating the source of power quality problems by eliminating the need for devising set points and calculating threshold values.

The ability to capture all the wave form data in high resolution in it's entirety over an extended period of time is the only way to ensure that the event will be recorded, allowing the engineer to analyze the data and define a solution.

Until now, monitoring and analyzing system electrical trends have presented a true challenge because certain data compromises were required to counteract capacity, processing and physical limitations. Data compression technology provides unlimited capacity for power quality data storage. This means that you are no longer required to set constraints on system data, rendering the risk in data selection based on set thresholds and triggers obsolete.

Operators of electrical networks are constantly faced with power events and transient occurrences that affect power quality and heighten energy costs.

In the past, to determine whether such events reflect system trends or isolated incidents, electrical engineers relied on partial information indicating what events occurred and when; not all events were recorded due to data capacity limitations and missed thresholds. Now, by analyzing multi-point, time-synchronized real-time power quality data, you can actually reveal why all power events occur and what causes them.

In short, data compression technology pushes power quality analysis capabilities into the next generation.on of several months or even a year depending on the network pollution level.
