The procedures for successfully controlling the on-load tap changers of power transformers in parallel have changed little for many years. The two most common procedures used today-minimum circulating current and master/follower- are well known and proven by experience. The most common implementations of each of these procedures, however, remain the traditional approaches of discrete analog circuits involving current transformers to ...

On-load tap changers (OLTCs) are electromechanical devices used in the voltage regulation of the electrical networks. A non-invasive monitoring method was developed using discrete wavelet transform (DWT) for condition assessment of on-load tap-changers using vibration analysis signals. The transient vibration signals emitted during a tap change are recorded and processed using spectral analysis and standards recognition techniques. The monitoring systems ...

Voltage control is considered one of the basic operational requirements of electrical power systems both at distribution and transmission levels. The most popular voltage control equipment includes On-Load Tap Changer (OLTC) transformer controlled by Automatic Voltage Control (AVC) relay, which is mostly used in 11 kV networks. In recent years, a growing number of distributed/embedded generators are connected to distribution ...

Condition monitoring of transformer windings has become a critical issue for proper asset management schemes in power systems. With the exception of on- load tap changers, transformer windings are the components most likely to fail, causing companies to incur heavy penalties. A new non-intrusive method for diagnosing the condition of transformer windings entitled "Transmission Line Diagnostics" (TLD) has been developed ...
