Electrical Testing and Commissioning

Electrical Testing and Commissioning

This Electrical Testing and Commissioning Training course covers practices and procedures that are essential to the safe start up of any electrical system for the first time, regardless of its size, type or industry.

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.

 

WHO should attend

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.

- Communication with client
- Oscillioscope records to laptop

Deficiency tracking
- Spread sheet

Program verification
- Force all critical faults and clear them...then do a dry run

Power up and start-up


Sensors

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

SCADA
- 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

- 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

Filters
- 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

Servo Systems
- Typically a bookshelf VFD systems configuration not requiring filters
- Fast actuating low voltage motors
