Power IQ Measurement & Analysis Software

Unique Features

Neptune ZIP Data Logging
Neptune ZIP is a unique patent pending technology that was designed to defeat the biggest challenge in power quality assessment - choosing the right data parameters to measure. Neptune ZIP takes the headaches away - ALL power quality related data, regardless of its severity, can be stored for any period of time. Neptune ZIP technology forever changes the way power quality history is stored, and provides the following performance advantages:
  • EVERYTHING you want to see is stores, meaning no more data compromises for recording speed

  • Years of data for every network cycle is recoverable with no data gaps

  • Thresholds and triggers are no longer needed, so you miss no events

  • All data parameters are recorded, so there is no need to select measurement parameters

  • Comprehensive power quality reporting and statistics for data analysis and report generation

  • True EN-50160 monitoring and analysis

  • Multipoint time-synchronized recording provides a true snap-shot for any period of time.

To perform Neptune ZIP data logging with the M3000, simply connect it to a computer running PowerIQ and activate the Neptune ZIP Logger application (a computer must be present during the logging process). Set the required accuracy and you're finished - no parameter setup, trigger or other constraints on the information you wish to record. When finished recording, use the Neptune ZIP Analyzer to create customized graphical trends, harmonic spectrum profiles, waveforms or text reports for each piece of data recorded during any period of time. Examples of Power Quality events which can only be analyzed using Neptune ZIP technology.

High Power LCR Meter

LCR meters are used to measure inductance (L), capacitance (C) and resistance (R). Typical LCR meters generate power to energize the load in a particular frequency and calculate the L, C & R. When power capacitors and inductors are measured, such meters don't have enough power to work properly. Moreover, they normally measure on single-specified freqencies. The M3000 uses the network power to energize the load and calculates the L, C & R on each harmonic present on the network, up to the 9th harmonic. This useful tool allows a user to analyze capacitor banks and inductors on multiple harmonics other than the fundamental. The LCR meter functions in single-phase network mode.

Record Dynamic Loads

In many cases power quality problems appear when the load changes rapidly. For example, motor startups an sometimes cause circuit breakers to trip, and spot welding generates voltage flicker. The M3000 allows the user to perform detailed analysis of these events and identify the power quality problem. Graphical cycle-bycycle load information can be displayed using PowerIQ software, from basic parameters of voltage and current to harmonic spectrum analysis up to the 63rd harmonic.

Supply Transformer Analysis

When a facility's electrical system is configured as a Delta network, the M3000 displays the phase-to-phase current and power, in addition to the line currents and total power. Line currents measured from the CT inputs are used to calculate the current and power inside the supply transformer (or generator). In completely balanced networks, the internal currents are simply 1/3 of the line currents. However, in most cases, the network is not completely balanced and internal currents are different than those expected.

Supply Transformer Analysis


This can be explained through the following simple example: A facility's transformer is designed for a maximum current of 2000A per phase, meaning each internal line is designed for a maximum of 1155A (2000/3). Assume the load includes a single, phase-to-phase load of 1900A connected between phase L1 and L2 and nothing on L3. Using simple math, the transformer appears to be 95% loaded (1900/2000). However, in actuality, the current is divided into parts - 67% on L1-L2 and 33% on each of L1-L3 and L3-L2. In reality, L1-L2 has 1267A, and the transformer is overloaded by 10% (1267/1155).




M3000 unique phase to -phase current and power algorithms display this information, enabling full and accurate network monitoring.

Multi-function Time-of-Use (TOU) Metering

The M3000 stores energy usage information (kWh, kVArh etc.) for every user-defined period. Its on-board memory records more than 2 months of 15-minute period data. TOU tariff calculations can be done in post processing, which allows the TOU to be defined after the data was logged. In locations where a user can choose between more than one TOU tariff, this becomes an effective support tool for tariff-based money-saving decisions.

PowerIQ Measurement & Analysis Software

This proprietary, easy-to-use software works in parallel with the M3000, allowing the user to display all system measurement results in a Windows operating environment. All network parameters, including harmonics, can be recorded continually or for user-defined, pre-selected intervals. Recording time is limited only by the size of the computer's hard disk or other storage device (server, memory card, etc). Electrical events can be captured by associating trigger values to various network power parameters, such as low voltage or high current. The event recording will capture a user-selected before and after window of time. PowerIQ has intranet and internet support capabilities.

LCD Display Screens

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 of their nominal value.

Wave form Screen

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

Harmonics Screen

The graphic display enables inspection of the complete harmonic spectrum and associated harmonic content 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.

Alpha-Numeric Screen

Alpha-numeric displays make the M3000 extremely easy to use. They are used for measurement screens (e.g., LCR and Energy meters), unit setup (e.g., Menus and help) and diagnostics (e.g., system information and system events). The screen displays up to 27 characters per line (max 16 lines per screen).
