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 347/600V AC) or using a Potential Transformer (PT). Minimum burden on the Current Transformers (CTs) is achieved by connecting the CTs without a physical contact. Delta network use 2 or 3 Ct's and Wye networks use 3 or 4 CT's.

Feeder Transformer Analysis 

When the system is configured as a Delta network, it displays the L-to-L current and power, in addition to the line currents and total power. The system measures the line current from the CTs and calculates the current 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 are different from these expected. 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%. Phasetrac's unique L-to-L current and power algorithm displays this information, enabling maximum network monitoring.

Main Menu

Large Digit Screen 

Permits simultaneous display of 9 parameters: 3 measured values plus 3 minimum and 3 maximum. Parameters can be mixed, such as average voltage, current and power factor. This unique feature allows analysis of the foremost parameters at a glance, without touching the unit. The PU % buttons displays the values as a percentage from their nominal rating.

Waveform Screen 

128 samples/cycle 
This large graphic display allows easy monitoring of transients of 130/156ÁS (at 60/50Hz). The display includes detailed information for each wave: the type and phase, THD, RMS, peak & bottom values plus value at cursor position.

Harmonics Screen 

63 harmonics
The graphic display enables inspection of the harmonics pollution at a glance. The display includes detailed information for each harmonic: type, phase, number of the harmonic, the value in amperes/volts and in percent, the angle and the frequency.

Power Monitoring Software 


This easy-to-use software displays the system's status, as well as the measurement results on numerous screens running under Windows (95, 98, me, NT and 2000). Power Monitoring Software integrates all Phasetrac systems, allowing power quality analysis, cost allocation, circuit optimization, demand & power factor monitoring. Power Monitoring Software includes real-time measurements, as well as comprehensive data logging and power quality analysis features. All screens allow customization, printing and exporting of data. The network version enables complete intra-net and Internet operation, as well as modem access.

Harmonics Analysis

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.

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. 


The event screen is used for retrieving, monitoring and analyzing the events information from the analyzer.


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.
