Motor Starting Study

Significance of Relay Coordination.

Motors are often started by connecting them to the supply line with a long lead. The lead draws a large current from the supply line, which is usually about five to seven times as much as the motor's rating. If this causes voltage drop in the supply line, it may affect other loads connected to the same supply line.

We offer motor starting study and analysis that determines the voltage drop and motor acceleration time as a result of starting a motor, as well as the consequences of motor starting on a system. The motor starting software used in the study conducted by this company analyzes the proper starting of motors on load with given system inertia. Other methods such as autotransformer, capacitor, across-the-line, or reactor are also studied. If system voltage is an issue, we will take action to ensure the system performs to expectations.

Importance of the Motor Starting Study And Analysis:

  • Due to low starting torques, the motor fails to start
  • Malfunctioning &Unnecessary tripping through under voltage relays.
  • Impact on other running motors connected to the other feeders.
  • Failure causes in other instruments, power supply, heaters, PLC, Computer systems.
  • Lights flickering & also reduce power quality, efficiency.

Process of Motor Starting study/Analysis:

Motor starting analysis is an essential part of power system engineering and takes place at the client site. This process involves gathering current and historical data, as well as information on the motor plate given by manufacturer. Based on this data, simulations are run by engineers through simulation software.

To predict the performance of new motor installations, we use both static and dynamic models. These models typically compare measured system parameters to theoretical values to predict the behavior of a motor. For dynamic models, we typically rely on simulated starting conditions that are based on the physical properties of the motor.

Types Of Motor Starting Methods:

  • Auto-transformers
  • Direct supply voltage with compensation
  • Direct supply voltage
  • Soft starters
  • Star-Delta Starters
  • Variable Frequency Drives (VFD)
