This course will aid participants in the understanding of On load tap changers (OLTC) and provide them with greater appreciation and knowledge of OLTC’s selection and function. The training is held at the Budin Philipp’s training facility.

At the end of the 3-day seminar participants will learn:

• How an OLTC works• To make decisions concerning OLTC with regards to operation, maintenance, troubleshooting• How the mechanical parts in your power transformer works.

Benefits of this course:

• We will provide 24/7 support should you encounter any issues with your products after attending our training

• Any money invested in our training and products can be recovered in your next maintenance cycle

• Our training sessions consist of theoretical elements but is unique in the practical element and participants will attain ‘real life’ knowledge

• We do NOT promote ‘death by powerpoint’.

COURSE PROGRAMMEDAYS 2 & 3

Participants will attain knowledge on the maintenance procedures for the different OLTC models:

Diverter Switch/Tap Selector

Selector Switch

• Safety briefing before working on HV equipment• General setup OLTC, Motor Drive Unit & Drive Shafts (Test Operations to bring the equipment into the “Adjustment Position”)• Checking OLTC position with Motor Drive position• Removing Drive Shaft protection cover• Removing horizontal Drive Shaft• Opening the OLTC head cover• Removing Diverter Switch insert• Replacing the cover• Diverter Switch support is removed• Energy Accumulator is removed• Diverter Switch is brought into middle position• Contact Shells are removed

During this process, participants will have the opportunity to attain hands-on experience with the equipment.

Once participants have gone through all the required steps of a routine service, they will then reassemble the Diverter Switch and reinstall the Diverter Switch into the compartment and close it.

Then, participants will perform a test operation to verify correct assembly. The final step will be to adjust the OLTC with the Motor Drive Unit.

Participants will also learn:

• Different ratings: 300, 350, 500 and 600 A Star point (3 Phase) OLTC• Modular set up of single phase OLTC 800, 1200 and 1500 A • Importance of symmetrical coupling OLTC and MDU• OLTC protective devices, RS2001, PRH, Diaphragm
