Integral Protection and Control Bay Unit as Terminal of a Distributed Bus Differential Protection
The IED generically called DRV integrates protection, control and metering functions for a great variety of applications, such as feeders, machine lines, frontier points, etc. DRV systems are designed for medium voltage lines, transformers, generators and feeders in general where a complete protection of the position is required, in Substations where it has been planned or it can be planned in the future, the installation of the Bus Differential Protection Unit
