Continuing Professional Development
The employees of the company "Delta Trafo" underwent training at the plant "Isolator" .
Continuing Professional Development
On December 9, 2015 the plant "Isolator" held a technical seminar  for the employees of the company "Delta Trafo" Ltd. on the topic  "Design, installation, operation and maintenance  features of high-voltage bushings."

The seminar was focused on the detailed and informative coverage of the topics of practical application:
1. The construction of high-voltage bushings for transformers. Applied internal insulation (RIP, RIN, paper and oil), its advantages and disadvantages. External insulation of bushings (polymer molding, polymer hollow insulator, porcelain lid). measuring terminal device. Units and parts of high-voltage bushings (central tube, condenser plates, screens, etc.)
2. The requirements for transport packaging. Proper storage of inputs prior to installation. Mistakes that can occur during installation of inputs (extension installation, the use of additional sealing materials). Violations of the operation rules of  the inputs (incorrect testing, installation of additional current transformers, the absence of control over input state).

For "DT": The achieved knowledge is already applied by the company specialists while designing of furnace transformers.
For "RIM": The achieved  knowledge is successfully used while conducting repairs of power transformers.
Employees of "Delta Trafo" Ltd. ( "RIM" Ltd.) who completed the training especially noted a  highly topical programme of the event, professional presentation of  information, the relevance of the illuminated topics. The management of the company "Delta Trafo" Ltd. is grateful to the  plant "Isolator" for the organization of training for professionals and individual approach.
Seminar: Accident-free Transformer 3.0
The seminar for managers and professionals responsible for uninterruptible power supply of enterprises will be held in Nizhny Novgorod.
Seminar: Accident-free Transformer 3.0
The topic of the seminar has attracted considerable interest among managers and professionals responsible for uninterruptible power supply of enterprises. More than 100 of current questions have been asked by experts after successful seminars in 2014 and 2015, more than 50 pre-entries were already sent for the participation in the 2016 open dialogue format seminar with the opportunity to share experiences with colleagues.

The basis of the insulation system of most powerful transformers makes paper (cellulose) insulation and transformer oil.

The seminar "Accident-free Transformer 3.0" is completely dedicated to the insulation system:

 Evaluation of insulation life;
 insulation failure mechanisms;
 Insulation Condition Assessment Methods;
 Examples of residual life assessment of transformers;
 What the average lifetime of transformers is;
 What affects the lifetime of a particular transformer;
 When the “zero hour” comes.

7 April: The seminar takes place in the congress center "Oka Premium" at the address:
Nizhny Novgorod, Gagarin Avenue, 27.

8 April: Study Tour to the production works of the company "Delta Trafo". During the trip the participants will be able to familiarize themselves with the magnetic core assembly process, manufacturing coils and paper insulation, as well as to explore the active part of an emergency transformer.

Registration for participants of previous seminars is open from 15 February.

For other interested persons - from 29 February.
