摘要： PROBLEM TO BE SOLVED: To provide a salt damage detector capable of previously, accurately detecting discharge of a facility of an actually used outdoor distribution line to be monitored.
SOLUTION: A pair of discharge electrodes 4A having an acute-angled pointed section 4a are disposed in an actually used insulator 1. Thus, an appropriate gap between the pointed sections 4a used as discharge parts can be easily set according to the environment of a field, and the partial discharge characteristic can be adjusted according to a dirt state of the insulator 1 surface. Accordingly, the actually used insulator 1 can be used as a sensor for salt damage prediction and monitoring, and the situation that the actually used insulator 1 of a real machine without using a simulation insulator or the like generates discharge by the salt damage can be detected previously and accurately.

摘要： PROBLEM TO BE SOLVED: To provide a salt damage monitoring system capable of detecting discharge light emission of an insulator being a monitoring object caused by salt damage, and of previously predicting the occurrence thereof.
SOLUTION: This salt damage monitoring system raises "discharge caution" when the system is brought into a weather condition and a state of the facility easily causing discharge light emission in response to a contamination situation due to salt damage of equipment 3 for power distribution of a monitoring object which is recognized based on weather data output from a weather information acquisition part 6 being the same facility for arranging a pilot insulator 5 therein, and arranged in a zone in the same weather condition, raises "caution needed" by determining that the system is in a situation where discharge light emission may occur when a moisture condition becoming a factor to lower a resistance value on an insulator surface in the state of "discharge caution" exceeds a predetermined threshold value, and issues "a salt damage warning" as discharge light emission occurrence when the occurrence of dry band arc discharge is confirmed from discharge detection data of the pilot insulator 5, whereby stepwise situation determination is enabled at main points up to the discharge light emission, and salt damage can be properly predicted in advance before the discharge light emission occurs.

摘要： PROBLEM TO BE SOLVED: To provide an aerial gas analysis/diagnosis method of a joint capable of diagnosing the existence of degradation of the joint without disassembling the joint based on the existence of specific diagnostic gas indicating that moderate discharge as a main object of the degradation diagnosis joint occurs, and to provide a structure of the joint.
SOLUTION: Aerial gas is sampled from the inside of the joint of a power cable using a gas sampling opening (S1001), and the type and concentration of the sampled gas are analyzed (S1002). It is investigated whether acetylene gas is contained in the sampled gas component (S1003), and, when acetylene gas is contained in the sampled gas component, it is determined that insulation degradation has occurred in the joint (S1004).
