Through Volterra Techniks, we offer the ACR PowerWatch Voltage Disturbance Logger—a practical solution for identifying and documenting intermittent voltage disturbances in single-phase electrical systems.
ACR PowerWatch
At Volterra Techniks, we provide ACR PowerWatch to help engineers, maintenance teams, facility managers and electrical professionals investigate unexplained power-related problems. Its plug-in design and event-based recording make it useful when disturbances occur intermittently and are difficult to identify during routine inspections. Rather than continuously recording electrical waveforms, PowerWatch monitors the supply for user-defined conditions and records the events that meet the configured thresholds. This helps users understand when voltage disturbances occur, how often they repeat and whether they coincide with equipment problems.
ACR PowerWatch Voltage Disturbance Logger
ACR PowerWatch is a compact, plug-in voltage disturbance logger designed for first-line power quality troubleshooting. It records time-stamped electrical events such as voltage sags, swells, outages, impulses, and frequency variations in supported single-phase systems. Many power-related problems are intermittent. Equipment may reset unexpectedly, electronic controls may behave inconsistently, or a machine may stop without an obvious fault. By the time a technician investigates, the supply may have returned to normal. PowerWatch helps address this challenge by keeping a record of detected disturbances for later review.
The device connects directly to a compatible electrical outlet, without requiring external probes, sensors, or access to an electrical panel for installation. Its compact design makes it suitable for monitoring a selected location while equipment continues its normal operation, subject to the installation requirements and electrical safety procedures applicable to that location.
Key Features of ACR PowerWatch
PowerWatch detects and records selected voltage-related events rather than continuously capturing waveforms. It can record:
– Voltage sags and dips
– Voltage swells and overvoltage events
– Power outages
– Voltage impulses or transients
– Frequency variations
These records help technicians investigate suspected supply disturbances and establish whether an event occurred during a reported problem.
Each recorded event includes date and time information. This makes it easier to compare logged disturbances with equipment resets, process interruptions, control-system faults, or reports from facility personnel. Instead of relying only on observations made during an inspection, maintenance teams can review a record of events that occurred earlier.
PowerWatch monitors voltage disturbances between hot and neutral, as well as between neutral and ground. Reviewing these measurements can help technicians investigate potential supply-side and facility-side electrical issues. This information supports troubleshooting, although further measurements may be required to confirm the source of a problem.
Users can configure voltage, impulse, and frequency thresholds through the supporting software. This allows the logger to focus on events that meet the selected criteria, helping make the resulting event record more relevant to the investigation.
PowerWatch can store up to 4,000 recorded events in non-volatile memory. This supports unattended monitoring over time, allowing users to retrieve and examine the event history after a monitoring period. A front-panel LED provides an indication that events have been recorded.
PowerWatch connects directly to a compatible outlet. It does not require external measurement probes or sensors, or specialist installation involving access to an electrical panel. This makes it a convenient first step when investigating suspected voltage disturbances at a particular location. The correct model must be selected for the supply voltage and plug configuration in use.
ACR EventReader software for Windows allows users to configure the logger, download recorded events, and review the collected information. The software provides summary views and detailed event reports to support troubleshooting and documentation. The recorded data can help teams review the timing and frequency of disturbances and decide whether further investigation is necessary.
PowerWatch uses the Lite-Link® optical interface for communication with a computer. Optical isolation maintains electrical isolation between the monitored circuit and the PC during data transfer, supporting safer data retrieval when used as specified by the manufacturer.
The logger draws operating power from the monitored electrical circuit. Internal battery support helps preserve timekeeping and recorded event data, including when the monitored supply is interrupted.

Typical Applications of ACR PowerWatch
PowerWatch is especially useful when a power-related issue is suspected but cannot be easily reproduced during a site visit.
01
Industrial Equipment Troubleshooting
Investigate unexpected machine resets, control-system interruptions, unexplained shutdowns, and inconsistent operation. Event records can help establish whether a voltage disturbance occurred around the time of the reported problem.
02
Commercial Buildings and Facility Maintenance
Monitor selected single-phase supply points in offices, commercial facilities, and building services where sensitive electronics or equipment experience unexplained interruptions.
03
Sensitive Electronics and Control Systems
Investigate power-related issues affecting computers, electronic controls, instrumentation, and power supplies. The recorded events provide supporting information for deciding whether more detailed electrical testing is needed.
04
Power Supply and Voltage Complaint Investigation
Document suspected voltage sags, swells, outages, and other disturbances when users report intermittent supply problems. Time-stamped records can help compare the reported symptoms with the events detected at the monitored outlet.
05
Maintenance and Service Diagnostics
Use PowerWatch as an initial diagnostic tool before arranging a more extensive investigation. The results can help technicians determine whether a suspected voltage problem has been recorded and whether advanced power quality instruments or additional electrical checks are appropriate.
06
Identifying Possible Supply-Side or Facility-Side Issues
Because PowerWatch monitors hot-to-neutral and neutral-to-ground disturbances, its records can support an initial investigation into where a problem may be occurring. Additional testing and professional assessment may be necessary to confirm the cause.
