Discharge estimation in a backwater affected meandering river [PDF]

, 2011
Variable effects of backwaters complicate the development of rating curves at hydrometric measurement stations. In areas influenced by backwater, single-parameter rating curve techniques are often inapplicable.

Partial discharge on-line monitoring for HV cable systems using electro-optic modulators [PDF]

, 2004
A technique for the remote inspection and monitoring of partial discharge (PD) activity using an optical network is described. The network uses a LiNbO3 modulator to modulate the intensity of the transmitted laser light approximately proportional to the ...

Challenges Associated with Implementation of HFCTs for Partial Discharge Measurements

, 2020
The stochastic nature of partial discharge (PD) and the inability to directly detect charge displacement makes representative measurement of such events very challenging.
