Configurable Solutions for Transformer Monitoring, Control and Communication

The DR-C50 Series of transformer monitors is a comprehensive monitor that is designed to be customer configurable, providing an economical solution for utilities’ monitoring, control and communication needs. Functionality includes basic cooling control with or without Voltage control, with or without OLTC / LTC monitoring and annunciation functions.

Advanced options include serial links, or Powerline Communications (PCS) to external devices for integration of on-line DGA, bushing and direct measurement of the transformer winding temperature via fiber optic sensors.

The product is provided with standardized wiring diagrams and is user configurable allowing a cost effective solution for most basic transformer applications.
