Intermittent fault investigations
Record relevant conditions around recurring trips, overnight stoppages or unexplained alarms. The aim is to capture information that a short site visit may miss and identify patterns worth investigating further.

Electrical data logging in Sydney.
Some faults disappear before anyone reaches the site. Altor offers data logging and monitoring to record electrical or process conditions over time, helping investigate intermittent issues in commercial, industrial, water and pump systems.
Intermittent faults
What happened before the equipment stopped?
Electrical loads
How does the load change during operation?
Process signals
Do readings change when the fault occurs?

THE WORK WE CAN HELP WITH
Start with the question you need answered.
The measurement, equipment and recording period should suit the problem. Altor discusses the site and symptoms first, then plans a suitable investigation and explains what the recorded information shows.
Electrical load monitoring
Monitor current, voltage or energy use with equipment selected to suit the installation and the question being investigated. Compare changes in the recorded measurements with the site’s operating periods and equipment use.
Process & instrument trends
Log suitable pressure, level, temperature or other available instrument signals. Reviewing changes over time can help explain equipment behaviour and support fault finding in water, pump and other process systems.
Review & practical next steps
Review the recorded trends alongside the reported symptoms and site information. Receive a clear explanation of the findings, the limits of what was captured and recommendations for further investigation or work.
PRACTICAL SITE SUPPORT
Useful when a single reading is not enough.
Equipment stops overnight
The plant is running during the day, but an alarm or stoppage appears at another time. A recording period can help capture the relevant conditions.
Loads vary through the day
Electrical measurements at one moment may not reflect normal operating changes. Logging can show how the monitored load varies.
A process issue is hard to reproduce
The relationship between a signal and equipment operation may be clearer when readings are reviewed over the same period.

This Altor photograph shows instrument signal testing at a control panel. Understanding the field signal and its wiring helps plan a logging investigation. The logger and connection method are selected separately to suit the measurements required.
How the work is approached.
To plan a useful recording period, discuss how often the issue occurs, the operating schedule and which electrical measurements or instrument signals are available. Site access, connection arrangements and the agreed monitoring scope are considered before equipment is installed.

Common questions about data logging.
How long does a data logging investigation take?
It depends on how often the issue occurs and the equipment involved. The recording period is discussed and agreed with you before work begins.
What equipment do you use for logging?
The logger and connection method are selected to suit the specific measurement needed — electrical load, voltage, or a process signal such as pressure or level.
What do I receive at the end of the investigation?
A review of the recorded trends against the reported symptoms, with a clear explanation of the findings and recommended next steps.
Can data logging be combined with a site visit or other electrical work?
Yes. Logging is often used alongside fault finding or maintenance work, particularly for intermittent issues a short visit might miss.

What do you need to find out?
Describe the equipment, symptoms, how often the issue occurs and the site location. Include the signals or measurements available, if known, and when the system normally operates.
