What is the Max Torque Angle for 32R protection for a MiCOM P343
Issue
User needs to determine whether a Max Torque Angle setting exists for the 32R (reverse power) protection element in the MiCOM P343 relay.
Product
MiCOM P343
Environment
Relay protection settings and configuration
Cause
Users may expect a directional protection element (such as 32R) to include a Max Torque Angle setting, as is common in other protection functions. This leads to confusion
when such a setting is not found in the relay configuration.
Resolution
There is no Max Torque Angle setting for the 32R (reverse power) protection element in the MiCOM P343 relay.
- The 32R function operates by measuring three-phase power using the calculation defined in the relay’s operation principles
- Directional determination is based on power flow direction, not angular relationships
- The relay only distinguishes between:
- Forward power flow
- Reverse power flow
Therefore, no torque angle adjustment is required or available for this function.
For detailed information on the operating principles, refer to the MiCOM P343 technical manual, which explains the power calculation and directional logic used by the relay.
