Abstract:

A synthetic partial discharge (PD) calibrator has been developed to qualify PD analyzers used for insulation diagnosis of HVAC and HVDC grids including cable systems, AIS, GIS, GIL, power transformers, and HVDC converters. PD analyzers that use high-frequency current transformers (HFCT) can be qualified by means of the metrological and diagnosis tests arranged in this calibrator. This synthetic PD calibrator can reproduce PD pulse trains of the same sequence as actual representative defects (cavity, surface, floating potential, corona, SF6 protrusion, SF6 jumping particles, bubbles in oil, etc

Abstract:

Main text High-voltage partial discharge (PD) tests require calibration of PD measurement systems using PD calibrators which provide known values of the apparent charge. A set of travelling reference calibrators was circulated among 14 participating laboratories and each laboratory reported apparent change and rise time measured using their own procedures. Comparison reference values (CRV) were calculated for each nominal charge level and calibrator and reasonable agreement of apparent charge calibration was reached. However, agreement of rise time measurements was unexpectedly poor. The scatt

Abstract:

The continuous, non-intermitted service of electrical grids relies on the reliability of their assets, e.g., power transformers. Local insulation defects can result in serve failures such as breakdowns with severe subsequent costs. The prevention of such events is crucial. Hence, partial discharge (PD) activity at power transformers is evaluated directly in the factory before shipment. Additionally, PD activity can be monitored during service using the ultra-high frequency (UHF) method. In this contribution, a calibration procedure is proposed for the UHF method. The calibration process is req

Abstract:

Partial discharge (PD) measurement is an established technique to detect local defects in the oil/paper insulation. They can be measured by electrical PD measurements according to IEC 60270 or by electromagnetic measurements in the ultra-high frequency range (UHF: 300 MHz – 3 GHz). The electromagnetic emissions of PD are recorded using an UHF sensor which is inserted into the transformer tank. The importance of PD measurements is reflected in the standard for charge-based electrical measurements (IEC 60270). Because of the standard, apparent charge, QIEC, became an essential factor for determi

Abstract:

Abstract A partial discharge calibrator is an instrument used to calibrate partial discharge detection equipment. Partial discharge refers to the phenomenon of partial discharge in insulating materials, which is one of the important indicators of aging and damage to insulating materials. A partial discharge calibrator can be used to detect and calibrate the sensitivity and accuracy of partial discharge detection equipment to ensure that it can accurately detect and monitor the partial discharge phenomenon in insulation materials, so as to timely detect and prevent the aging and damage of insul

Abstract:

This article offers an alternative method of calibrating partial discharge meters for research and teaching purposes. Most current modern calibrators are implemented as precise voltage pulse sources with a coupling capacitor. However, our calibrator is based on the physical principles of dielectric materials distributed in a plane or space. Calibrator design is unique and there is an attempt to get closer to the behavior of the measured real objects. The calibration impulses are created by energy from a high voltage power supply at the specific or nominal value of the applied voltage. At the s

Abstract:

This paper presents the application of a programmable partial discharge calibrator, which used to test the performance of four partial discharge measuring systems by injecting a program controlled known charge sequence into the device under test. Performance of linearity, response to opposite polarity pulses, pulse resolution time and response to random pulse sequence are compared and the results obtained show that the tests prescribed by the standards do not fully characterize the partial discharge measuring system behavior.

Abstract This article displayed the method of partial discharge (PD) measurement in high-voltage insulator and calibrating the effective element (capacitor) to enhance the PD signal. The cavity shapes were plate–plate, cylindrical and spherical inside the solid insulator. The proposed system enables from detecting the reverse and main discharge, respectively, through the rise and tail time of the pulses. PD that took place was bounded with internal cavities. Proteus simulator and Matlab simulation models were used to measure and display the PD signal. The results showed PD-calibrated waveforms

Abstract:

During the monitoring, management and protection of electrical plants, networks and devices, regular measurement of various quantities is necessary. First of all, current and voltage measurements are basic. In this paper, attention is directed to voltage inductive transformers. The insulation is made of oil and it is necessary to regularly check the condition of the insulation in order to determine the need for its replacement. Of the many measurements that are made in practice, this paper will talk about insulation resistance and partial discharges in oil. Moisture and impurities mostly affec

Abstract:

Streamflow influences the distribution and organization of high water marks along rivers and streams in a landscape. The federal definition of ordinary high water mark (OHWM) is defined by physical and vegetative field indicators that are used to identify inundation extents of ordinary high water levels without any reference to the relationship between streamflow and regulatory definition. Streamflow is the amount, or volume, of water that moves through a stream per unit time. This study explores regional characteristics and relationships between field-delineated OHWMs and frequency-magnitude
