Protective Relay Acceptance Testing
The relevance of acceptance testing is constantly growing along with the increasing number of relay providers and relay models. Depending on what needs to be tested, either a function-based or a simulation-based (black box) approach is the right option. In addition, it can be a challenge to handle the firmware updates that come with modern relays. Often new firmware is tested in the utility lab before it is applied to all the other devices in the field.
