Power system transients, which are caused by events such as switching operations or lightning strikes, can lead to equipment damage, misoperations, or widespread performance issues. These disturbances range from high-frequency spikes that threaten sensitive electronics to lower-frequency oscillations that carry significant energy and propagate far from their source. Effects often include nuisance tripping of power-electronic devices and abnormal voltage or current deviations until system stability is restored.

KLS Power Consulting uses EMTP-RV and PSCAD to perform detailed electromagnetic transient studies that identify, evaluate, and mitigate these disturbances, supporting system reliability, protection coordination, and sound equipment design. Services include:

Our electromagnetic transient (EMT) studies focus on analyzing the fast-switching dynamics and high-speed interactions in electrical systems. We use PSCAD and EMTP RV tools to simulate and analyze:

• Substation Insulation Coordination and Surge Protection Design
• Coordination of Surge Arresters with Transformer BIL
• Shielding Effectiveness and Lightning Performance of Substations
• TOV (Temporary Overvoltage) Studies: Assessing voltage surges during transient events and designing mitigation strategies.
• TRV (Transient Recovery Voltage) Studies: Analyzing voltage recovery following a fault to ensure equipment protection.
• Switching Transients: Examining the impact of switching operations on system components.
• Lightning Protection: Evaluating the effect of lightning strikes on system equipment and designing protection schemes.
• Capacitor Bank Switching (Energizing and Switch Restrikes)
• Outrush Reactor Transient Recovery Voltage Analysis

These studies help ensure that substation equipment is protected from fast transient events and that the system operates reliably during disturbances.
