Harmonic values: n,i - phase difference between phase voltage and mains current at the n'th harmonic and phase i RMS Values: Pi - total active power (for all harmonics) at phase i Qi - total reactive power (for all harmonics) at phase i -P - total active power (for all phases) -Q - total reactive power (for all phases) Applications Network Types The Power Analyzer supports any network connection configuration, such as 3 and 4 Wire, Wye and Delta, and single-phase. The connection is either direct (up to 347/600 VAC) or using a Potential Transformer (PT). Minimum burden on the Current Transformers (CTs) is achieved by connecting the CTs without a physical contact. Delta networks use 2 or 3 CT’s and Wye networks use 3 or 4 CT’s. Feeder Transformer Analysis 1900A When the system is configured as a Delta network, it displays the L-to-L Max. Rating: 1155A current and power, in addition to the line currents and total power. The Actual: 1267A system measures the line current from the CTs and calculates the current 1900A and power inside the feeder transformer (or generator). In completely balanced networks, the internal currents are 1/33 of the line currents. In many cases, the network is not balanced and the internal currents 1900A are different from these expected. Load This can be explained with the following hypothetical example: A transformer designed for a maximum current per phase of 2000A, therefore each internal line is designed for a maximum of 1155A (2000/33). The network includes only one phase to phase load of 1900A between phases L1 and L2 and nothing on L3. The transformer appears incorrectly to have a 95% load (1900/2000). The currents are divided into 67% on L1-L2 line and 33% on L1-L3 and L3-L2 lines, resulting in 1267A on the L1-L2 line, and the transformer is overloaded by 10%. Elspec’s unique L-to-L current and power algorithm displays this information, enabling maximum network monitoring.

POWER ANALYZER Harmonics Analysis Scope Displays the harmonics spectrum both as a graph and as a table, in addition to harmonics analysis parameters (THD, K-Factor and Crest-Factor). Compliance monitoring of international power quality standards, such as IEEE-519, allows easy network analysis. Displays waves and their phase shifting, and enables detection of existing or potential power quality problems. Data Logging Enables comprehensive network analysis by logging over 2000 parameters per record. It can be set to record data either on pre-defined intervals (from 1 cycle to 99 hours) or according to network events. The recording volume and time is limited only by the size of the computer’s hard disk. Data Monitoring Displays the recorded data in either on-line or off-line mode. The on-line mode displays the data while simultaneously recording it for maximum power analysis control. Report Generator Creates user-defined or preset reports (such as load profile and power quality) reports. The reports are easily defined using a word processor (such as Microsoft Word). Time-of-Use (TOU) Displays the Time-of-Use information stored in the analyzer, in addition to calculation of energy costs, according to virtually any utility tariff structure. Events The event screen is used for retrieving, monitoring and analyzing the events information from the analyzer.
