Single Phase Motor Application

Description

TeSys Tera system can support the three-phase or single-phase motor.

In starter settings, select the required type of motor as three-phase or single-phase from the parameter setting. Default configuration will be three-phase.

Disabled Functions

In single-phase mode, following functions are disabled:

• Metering functions:

  • Current measurement : IL2 and IL3 RMS currents, current phase sequence, average current and current imbalance. 

  • Voltage measurement : VL2-L3 and VL3-L1 RMS voltages, voltage phase sequence, average voltage and voltage imbalance. 

  • Calculated ground current.

  • THD measurement of L2 and L3 current and voltage. 

• Protection functions:

  • Current imbalance, current phase loss, and current phase reversal protections.  

  • Voltage imbalance, voltage phase loss, and voltage phase reversal protections.

  • Calculated ground fault protections.
