The ACE 2000 is an advanced single- and three-phase power analyzer featuring energy, harmonic, transient, and flicker analysis capabilities. The ACE 2000 can be used for measurements of monophase and three-phase power systems with three- or four-wire configuration. The instrument's high-speed data-acquisition system, powerful user interface, and graphics display affords a large breadth of measurement capability, making it a valuable resource tool in electrical power-quality analysis.

The ACE 2000 has 8 fully insulated analog input channels and 4 digital channels (2 input and 2 output). Simultaneous high-resolution sampling of voltage and current channels plus fast digital processing enable period-by-period power analysis for 50/60-Hz lines. The instrument's dual processor architecture allows for high-measurement accuracy even on distorted waveforms, along with a powerful data management capability in the form of real-time displays and monitoring of all measurements.


The ACE 2000 measures and describes all aspects of power consumption. Measurement capabilities include RMS voltage, RMS current, true power, apparent power, reactive power, true power factor, frequency, active energy, and reactive energy. Each measurement is computed every period (for 50/60-Hz lines). The ACE 2000 provides minimum, maximum, and average values observed for meter readings during user selectable intervals ranging from 1 to 9999. For more flexible demand analysis, energy values may also be grouped into four different daily and weekly programmable periods.
Built-in harmonic analysis capabilities provide the user with THD and spectrum reports up to the 50th order for all voltage and current channels simultaneously. For power measurements, harmonics are compared to set threshold levels in order to detect out-of-limit values. This permits the user to monitor potentially damaging


The ACE 2000 functions as a versatile recorder. Measured data can be stored in a normal mode, alarm-on thresholds (one or more measurements exceeding their selected thresholds), or via an external trigger (input channel 1 or 2) with user definable start and stop dates. Recording intervals may be selected between 20 ms and 1 hour. Alarm events can be independently stored along with specific information such as peak value, duration, and time. The ACE 2000 provides 4 different archival spaces for power, harmonic, transient, and flicker harmonic measurements. With more than 3.2 GB of storage capacity, extensive measurement data can be captured.


The ACE 2000 has a built-in downloading feature for upgrades and emerging application-specific packages (impulse analysis, high-frequency noise analysis, etc.). With a simple application disk, the user can reconfigure the instrument and immediately obtain an upgraded version providing new features and functionality.


Users rely on the ACE 2000 to solve many kinds of power consumption and quality problems. The ACE 2000 is used by T&D facilities, electrical construction and maintenance companies, hospitals and medical labs, electrical generating and machinery plants, consulting engineering groups, and telecommunications providers.


A wide high-contrast graphic display and a 20-key functional keyboard with rotary knob make the ACE 2000 simple to operate. Fully menu-driven, the operator interface displays readings in an easy-to-understand manner, allowing simple, straightforward programming procedures.


The Transient module, completely integrated with the system, captures transient events on all voltage and current waveform channels. It is possible to define internal triggers based on RMS values, threshold levels, a monitored channel, or activated digital output. Moreover, two "smart-mode triggers" can be set to trigger on slow and/or fast disturbances. The system can handle up to 16 triggers simultaneously and combine them into logical expressions affording users maximum operating flexibility. The recording length of the event can be programmed from 40 ms to 1.8 s, including a pre-trigger and a post-trigger time. The number of events that can be recorded is practically unlimited (3.2 GB). The event trace can be graphically analyzed on the instrument's display, printed directly through the parallel port or transferred to a PC for further analysis.


The new IEC 868 normalized flicker meter is designed to measure any quantity of flicker sensation through statistical analysis procedures to obtain short- and long-term severity flicker indicators such as (CPF, P50%S, P10%S, P3%S, P1%S, P0.1%S, PMAX, PST, PLT) having a voltage input frequency from 50 Hz to 60 Hz.
