| A fully operational digital protective relay or Intelligent Electronic Device (IED) are provided for protecting electrical equipment of a power distribution system. The relay includes an input module, a processing module and an output module. Signals received from current transformers connected to the input module are evaluated by the processing module, and in reaction thereto, trip signals can be output to an actuator of a circuit breaker via the output module. A base Human Machine Interface (HMI) enables a user to enter operating parameters such as a delay time or nominal current to the processing module. Optionally, a further HMI may be attached to the protective relay and connected, via a suitable interface for data exchange, to the processing module for the purpose of displaying protection-related information to a user. This further HMI is both optional and detachable. For example, the further HMI can be repeatedly attached to and detached from the protection device. The detachable HMI provides for an increased flexibility in the use of the protective relay, as a user may adapt its interfacing capability by acquiring a detachable HMI of the type and at the time that best suits his evolving needs. | ||||||
