An update on the paralleling of OLTC power transformers

P. Okanik; B. Kurth; J. H. Harlow 1999 IEEE Transmission and Distribution Conference (Cat. No. 99CH36333), 1999

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 ...


Experimental model of aging mechanisms of on-load tap changer contacts

Jur J. Erbrink; Edward Gulski; Johan J. Smit; Paul P. Seitz; Rory Leich 2008 International Conference on Condition Monitoring and Diagnosis, 2008

It is known that most failure of power transformers are related to aging effects of the on-load tap changer contacts. To understand the aging mechanisms and to develop knowledge rules to interpret different failure mechanisms a test model has been developed. In particular, the effect of the several aging stages of tap changer change-over selector contacts on dynamic resistance measurements ...


An investigation into the OLTC effects on voltage collapse

T. X. Zhu; S. K. Tso; K. L. Lo IEEE Transactions on Power Systems, 2000

It is known that following disturbances, on-load tap changers act to restore the load bus voltage and thus restore the load power to near pre-disturbance level. As the system is probably weakened by the contingencies, this will often over-tax existing supplies due to increased losses and reduction in power plant ability, and thus voltage collapse may result. This paper discusses ...


Self-Organized Classification of On-load Tap Changers Acoustic Signatures

Eduardo F. Simas Filho; Luiz A. L. de Almeida 2008 IEEE Instrumentation and Measurement Technology Conference, 2008

On-load Tap Changers (OLTC) are widely used for voltage regulation in electricity networks. A set of electrical contacts (taps) is used to change the transformer input/output ratio as the input voltage varies. Non-invasive acoustic methods for condition monitoring of internal electrical contacts have been recently proposed in the literature. A limitation of these analysis is that there is no information ...


Possible effects of smart grid functions on LTC transformers

E. Tom Jauch 2010 IEEE Rural Electric Power Conference (REPC), 2010

This paper focuses on Load Tap Changer (LTC) transformer duties associated with SMART GRID (SG) Integrated Volt/Var/kW Management (IVVM) functions. Implementation of SG technology, with resultant changes in power systems, may cause increased or excessive tapchanger duties. These duties will be affected by a) the integration of renewable energy sources; b) more precise operational voltage control levels for conservation voltage ...
