Electrical Testing and Commissioning is a very special occurrence and poses some unique challenges to electrical personnel. Inexperience and poor planning will inevitably result in prolonged delays in the start up which can lead to costly productivity losses. This course provides invaluable information to anyone who wishes to know and understand the role of Electrical testing, troubleshooting and commissioning of electric power systems.
The importance of planning and preparation for the project, from engineering to testing, troubleshooting and commissioning and eventual start up, will be emphasized. This course deals with safety considerations and testing and start-up procedures for all the components of any electrical system. The course leader will also offer useful guidelines on what to do when things go wrong during this phase of a project. This course provides guidelines to anyone who wishes to know and understand the role of commissioning in a project, whatever its size. The importance of planning and preparation for the project, from engineering to commissioning and start up, will be emphasized. This course includes the safety considerations in maintenance and testing procedures for all the components of any electrical system.
This Electrical Testing and Commissioning course focuses on the building blocks of sound electrical maintenance fundamentals and electrical design, and then integrates that informatio.
It begins by reviewing basic electrical circuits and electrical laws. You are then exposed to the basic principles of electrical generation, transmission, and distribution. Electrical distribution is covered in considerably more detail, followed by power system protection and its components in terms of isolators, fuses, and circuit breakers.
The Electrical Testing and Commissioning course continues with an examination of AC and DC motors and lighting and illumination. Other major topics include electrical safety, national codes, and customer installations.
Design engineers, electrical engineers, commissioning and testing engineers, consulting engineers, electrical technologists, project managers, project engineers, plant managers, operating and maintenance personnel and all individuals involved in electrical equipment maintenance, testing and commissioning project execution.
Management of Start Up & Commissioning Projects
- Kick-off meeting/project management meeting with the client and prime contractor
- Establish clear understanding of the directive priorities
- Understanding that priorities WILL change based on project phase
- Redline drawings and colour coding knowledge
- Re-CAD if it's contractual
- Drawing clouds for future possibilities
- RFI, NCR, TDR, IFI, IFC, etc...
- Completions to turnover
- Potentially training client staff on operations after turnover
- IEEE, CSA, ULC and client standards which in most cases exceeed all
- Daily update on all drawings and programming cut sheets
Drawing control, field mark ups and "as built"
- Always have both hard and soft copies...preferably in document control dept. and usb...if there is no paperwork, then it didn't happen
Test sheet document control
- Keeping track of completed tasks via spread sheet or Gantt chart
- Communication with client
- Oscillioscope records to laptop
- Spread sheet
- Communication with client project manager
Commissioning Electric Power Systems
Large Area System Commissioning
Ensuring the system is working completely
- Bump check for rotation
- Motor burn in
- Load test minimum 75% of full load
- Fault and alarm forcing via DCS or SCADA
Using electrical drawings & flow-sheets
- Loop check
Isolating devices and isolating points
- Force the trip and clear it from DCS or SCADA
- De-energize and test point to point to loop check all circuits back to the controller if an issue arises
General Construction, Operation & Safety
- Morning safety meeting
- PERMITS, JSA, FLRA and workface discussion to let others know what you are doing
- NOMEX III
- Overhead awareness
- Fall arrest harness
- CLEAR safety Glasses
- Speed limits
Field Assembly and Vacuum Filling of Power Transformers
- Handling Transformer Oil, Tap-changers
- Transformer Protective Devices, Bushings, auxiliary devices alarms & trips
- Dry type transformers: inspection, acceptance tests
- Liquid type transformer: inspection, and acceptance tests
- Routine transformer tests: AC high potential testing, polarity test, induced potential test, polarization index test, and DC winding resistance tests
- Transformer Oil test, On Power and Off Power Expectation.
- Breakdown voltage test
Circuit Breaker and Switchgear Commissioning
General Construction, Operation & Safety
- Find the feeder and ensure lockout/zero energy state with YOUR lock on the lock box
- Work with operations on the actuation of the auxillary contacts to close the breaker and/or vacuum bottles with zero line side voltage
Metal Clad Switchgear construction and safety features
- Kirk key interlock or similar
- ARC rating labeling, bolted doors, and window with exterioer visual disconnect indication that stabs are out
600V Breaker construction and safety features
- Mechanical disconnect, fusing and overload relay if available
Multimeter on low voltage or applied 120VAC with clamp on ammeter if medium voltage
- Turns ratio impedance test
Instrument Transformers, Test switches, Metering and Relaying Devices
- Work with DCS to trigger various alarms and faults
Insulation resistance measurement test
DC or AC hi-pot testing
Power factor or dielectric loss test
Circuit breaker contact resistance test
Commissioning Control Systems and Instrumentation
- Calibrate depending on the device
Input and outputs
- Loop check back to the PLC
- Force all critical faults and clear them...then do a dry run
Power up and start-up
PLC and PAC Based Systems
- Ensure that you can see that the field devices are reporting to the controller AND that the scaling is correct
Distributed Control Systems
- Work with the PLC on communications and ensure that the DCS is reading what the PLC is sending
- Much the same as DCS, however more components involved
Commissioning Motors and Drive Systems
Motor checks and testing
- Disconnect the line and load to perform a free rotation test on the shaft front and rear bearings
Wiring & Cable Run
- Ensure that the cable run doesn't exceed the maximum length resulting in capacitive cable charging requiring filtering
VFD checkout and start-up
- For LV you need to test your line and load side de-enegized...SCR's on the front and IGBT's on the back for LV. SGCT's and GTO's depending on MV vitage
- Program the motor nameplate data into the main controller
- Volts per Hertz doesn't require tuning the drive, however sensorless vector requires tuning, but is more accurate while full vector control is most accurate
- Uncoupled rotation test with communication with operations (DCS or SCADA)
- Coupled run with the application
- Remove common mode capacitor on neutral grounded resistance electrical supplies
- Sinusoidal filters are an inductive filter that smoothes out the pulse modulated current frequency current signal only from a VFD, while leaving the PWM voltage alone
- LRC filters smooth out both voltage and current, resulting in harmonic reduction and increased cable run possibility
- Typically a bookshelf VFD systems configuration not requiring filters
- Fast actuating low voltage motors
