  • Priority Table Rationale for Electrical Substations
    It would seem that every thermographer has their tried and true approach to determining the severity of a heating component. In the electrical utility industry, the decision to remove a heating component for repair is not a trivial one. Generation may be bottlenecked, customer's supply put at risk
  • Troubleshooting Infrequent Alarms in a Substation
    CAS DataLoggers recently provided a dataTaker DT80 datalogger for a manufacturer experiencing 'Under Frequency' alarms at their electrical substation which were slowing production. Maintenance staff wanted to log their power levels, but the infrequent nature of these faults meant that they would
  • Improving Measurement Accuracy with a Thermal
    are very important and aid in obtaining the correct temperature value. For those of us who are scanning electrical substations with thermal imagers, it is very important to obtain the correct temperature. There are several criteria that help us to determine the course of action to be taken based
  • How Thermography is Carried Out for the National Grid in New Zealand
    and carrying out the repair. INTRODUCTION Transpower owns the National Electrical Grid in New Zealand and takes the maintenance of its substations very seriously. ABB Limited (along with other contracting companies) carries out scheduled maintenance on substation and transmission lines for Transpower
    generation and distribution and other industries makes us supremely confident in bringing to market. " SNAP-DNP I/O connects to virtually any electrical, electronic, or mechanical utility device or system via a broad array of optically isolated and guaranteed for life analog and digital modules
  • Using Modular DC/DC Converter for Industrial/Electricity Related Applications
    This application note underlines the different. requirements in electronic systems used in. Electrical Power Plant, High Voltage Substations,. Telecontrol Centers or Low Voltage Distribution. Controls. Electronic systems in such applications are subjected. to harsh environment constraints from
  • Predicting and Preventing Transformer Outages in a Steel Mill
    crews rely on condition monitoring technologies like ultrasound inspection and infrared. imaging to predict electrical component failures in all systems including substations, MCC gear, transformers, and the like.
  • Adjusting Severity Criteria
    has forced me to adjust my severity criteria for specific IR anomalies. This paper highlights two cases where sticking to the standard IR severity criteria would have resulted in a disaster. I have been doing substation and electrical maintenance for over 35 years. For the last 14 years, I have
  • Arc Flash Concerns & Detecting Early Signs (.pdf)
    , metal clad switch gear, pad mount transformers, and other electrical equipment, has risen, along with the available fault current.
  • Instrument and control
    Instrument and control switches are used to manage relatively large currents and voltages as found in operator panels at electrical utility substations. switches are used to manage relatively large currents and voltages as found in operator panels at electrical utility substations.
