The Japanese Electric Wire & Cable Maker's Association established the most appropriate current for power cables with economy (LCC) and environment (LC-CO2) in mind (ECSO current) as one of the Japanese Cable Makers' Association Standards (JCSs). The ECSO current is intended for low-voltage CVT cables used commonly in factories and buildings. In addition,a questionnaire and interview with persons who are involved in the design of electric facilities in factories and buildings were conducted to investigate the daily load curve,annual number of operation days,demand factor,duty factor,distribution of cable line length,and other cable usage conditions. According to the investigation results,the authors have estimated reductions in distribution losses and CO2 emissions when all low-voltage CVT cables in sites of consumers (factories and buildings) in Japan (1,830 thousand km) are switched to those with upsized conductors based on the “ECSO current table.”The estimation has revealed that the total annual reduction in distribution losses in Japan is 210 hundred million kW・h,which is the equivalent of the output of 4 one-million kW-class large power plants (53 hundred million kW・h per plant (60% operation) ). It has also found that the total annual reduction in CO2 emissions in Japan is 11.6 million tons,which is determined by subtracting an increase in CO2 emissions resulting from the increased copper production. This accounts for 0.9% of 1,261 million tons,which is the total CO2 emissions in Japan in the base year (the year 1990) of the Kyoto Protocol. Japan has been considering various measures for further reduction of CO2 emissions even after the fulfillment of the commitment to 6% CO2 reduction described in the Kyoto Protocol. Since upsizing low-voltage CVT cable conductors can be expected to reduce the total CO2 emissions in Japan of 0.9%, it is one possible effective measure.

In this study, the author investigated the online deterioration diagnosis of hydro-generators. Simultaneous measurements were done under offline conditions by using an online PD monitor and an offline PD measuring system. When a stator had wave-winding structure, good correlation between the maximum electric discharges and PD values of the online PD monitor was seen. However, when a stator had lap-winding structure, a good correlation could not be seen clearly. PD values were small due to the weak capacitive coupling in a lap-winding structure. PD measurement of hydro-generators with wave-winding structure was done under online and offline conditions by using the PD monitor. Online PD values were slightly higher than offline PD values. The author believes that online PD monitoring is useful in diagnosis of hydro-generators when the stator has wave-winding structure.
