Dry distribution transformers
TMC Bulgaria represents part of the TMC Transformers group, which has branches in countries such as Australia, Italy, Spain, Argentina, France, Germany and Israel. The company produces dry epoxy transformers with a range of 100 kVA up to 10,000 kVA, which are suitable for installation in premises with high requirements for ecology and fire protection. Our transformers are characterized by high reliability and quality, solid construction, long service life and low noise level. The TMC Group engineering team offers standard transformers, transformers with reduced losses, special types of transformers with specific winding according to the customer's request (traction transformers, for frequency converters, with double winding MV or LV).
Transformers are tested in CESI laboratories in compliance with environmental class E2, with climate class C2, with fire resistance class F1. All our transformers undergo routine tests, and we also offer some special tests at the customer's request.
Routine tests include:
- Measure the ratios and check the phase shift and confirm the type of connection
- Measurement of losses and no-load current
- Measurement of short-circuit losses and load losses
- Tests with applied voltage
- Tests with attached voltage
- Measurement of partial discharges
- Verification of documentation
- Accessory verification
- Verification of dimensions
Special tests include:
- Thermal load
- Impulse voltage test
- Noise level measurement
