GE BDD15B11A Transformer differential relay Fast delivery time

GE BDD15B11A is a percentage differential with harmonic restraint relay. It is used to protect transformers rated 2000 kVA and above, as well as transformers with windings rated 15 kV or above.

The relay has two primary windings, one for each line current transformer circuit. The harmonic components are separated from the fundamental component by suitable electric filters.

The relay has a number of features that make it ideal for transformer protection, including:

• High sensitivity and selectivity
• Fast response time
• Immunity to harmonics and other disturbances
• Adjustable operating characteristics
• Comprehensive self-monitoring and diagnostic capabilities

The GE BDD15B11A relay is a reliable and effective way to protect transformers from a variety of faults, including:

• Phase faults
• Ground faults
• Overloads
• Turn-to-turn faults

The relay is available in a variety of configurations to meet the specific needs of different applications. It is also backed by GE's global support network.

Here are some of the key features and specifications of the GE BDD15B11A relay:

• Percentage differential with harmonic restraint relay
• For the protection of transformers rated 2000 kVA and above and for transformers with windings rated 15 kV or above
• Zero Restraint
• Pickup
• (A)

The relay is typically used in power substations and industrial facilities. It is a critical component of the electrical protection system for transformers.
