The BTB Controller and DEIF AGC 150 Series: Synchronisation, Protection, and Power Management

In modern power systems, reliability and efficiency depend on advanced controllers that ensure synchronisation, protection, and monitoring. DEIF’s BTB controller and the AGC 150 series represent a comprehensive range of solutions tailored to various applications—ranging from bus tie breaker management to genset, mains, and hybrid control.

BTB Controller: Synchronising and Protecting Bus Tie Breakers

The BTB controller (Bus Tie Breaker controller) is designed to synchronise one breaker while protecting and monitoring the busbar. It plays a vital role in balancing loads, improving power distribution, and maintaining grid stability.

When integrated with DEIF’s Power Management System (PMS), the BTB controller can handle up to 8 bus tie breakers, enabling advanced load-sharing and seamless power transfer. This makes it particularly valuable in critical facilities such as:

• Data centers
• Industrial plants
• Marine vessels
• Utility substations

With real-time monitoring, operators benefit from enhanced fault detection, operational safety, and optimised energy use.
