During the commissioning stage, testing medium voltage soft starters in low voltage mode is crucial. Simulations for starting a MV motor play a vital role in ensuring a smooth transition.

One key aspect is the pre-commissioning stage, where verifying all I/O functions and the gate firing control for the SCR's is essential for optimal performance. This process guarantees that all components are functioning as intended before full operation.

Overall, conducting these tests and simulations at various stages is a proactive approach to address any potential issues and ensure the successful operation of medium voltage soft starters.

Our client from Nigeria, in collaboration with their user representative, recently attended here in Great Yarmouth a two-day testing session for three pieces of 200A 3.3kV soft starters. These starters are designated for installation in their new residence just outside Port Harcourt, housed in brand new 20-foot air-conditioned containers. The soft starters will be tasked with powering 355kW centrifugal oil pumps.

Each container will be connected to a feeder panel equipped with a changeover cabinet, allowing seamless integration with any of three 1MW generators. The comprehensive testing encompassed various assessments, including a Hi-Pot test at 7.2kV lasting 60 seconds, a full functional test, operational procedures under no load conditions, lock-off assessments, and evaluation of electro-mechanical interlocks. Additionally, a full I/O test was conducted, meticulously verifying all manual inputs and output interlock signals for optimal performance.

Finally using the smart commissioning feature in the MVE Series we made a series of soft starts using a low voltage motor at 400vac simulating a medium voltage start.

This rigorous testing ensures the smooth operation and reliability of the soft starters, highlighting the commitment to quality and precision in our client's upcoming project.
