Fluctuations in Power

Cena 2YA Suffers Damage ECENT fluctuations in the main electric power supply affected the transmissions from 2YA on the evening _of Monday, February 25, and again on the afternoon of Tuesday, February 26. The surges were so Severe that the relays at the transmitter were damaged, and as a result the station was off the air for some time in each case, At 9.10 on Monday evening there was a very heavy surge in the power supply, which was noticed all over the city, and this blew two main fuses, all the fuses on the top bank of filters, and put out of action the oscillator plate current meter of 2YB. Repairs were completed by 9.30 p.m., and transmission resumed. On the Tuesday afternoon another surge occurred at about 2.45 p.m., when the station was starting up, and put the plant out of action. On attempting to restart it was found that damage had been done in the D.C. control panel. The nature of the trouble was evidently located in burnt-out leads to the relay contact, and 2YA was able to start transmission at 4p.m., but after a few minutes the station again went off.
