Diesel generator set detection false load
2021-09-10
All kinds of diesel generator sets and UPS (uninterruptible power supply) are used as emergency standby power supply after municipal power failure or power failure. Most of the time, the diesel generator set and UPS (uninterruptible power supply) are in standby state. In case of power failure, the diesel generator set is required to start power supply immediately, otherwise the standby diesel generator set will lose its significance.
Practice has proved that strengthening the daily inspection and maintenance of diesel generator set can effectively avoid accidents. Only by establishing perfect inspection and maintenance procedures for diesel generator sets and regularly and regularly maintaining, maintaining and testing diesel generator sets, can we prevent them from happening.
According to the latest investigation of many grass-roots maintenance personnel, the common maintenance technical problem in power supply maintenance is that the detection of output power and electrical characteristic parameters of various diesel generator sets and UPS equipment has not been carried out effectively and smoothly without high-power AC dummy load, Only after the power supply failure occurs can it be known that the performance of diesel generator set or UPS (uninterruptible power supply) has a problem.
