The effect such as it is mainly used in measuring, protect and monitor.When the primary and secondary failure of transformer, substation secondary voltage is
Missing, causes the missing of protection, metering and monitoring, and the missing of protection can cause potential safety hazard, and the missing measured can be caused
The loss of business economic, and the missing monitored can then influence judgement and analysis of the operations staff to equipment running status, thus it is secondary
The effect of voltage is highly important.And the failure such as fuse melting of transformer substation voltage transformer causes lacking for secondary voltage
Lose, in order to find secondary voltage failure, it is necessary to be monitored to secondary device voltage in time, improve secondary voltage monitoring capability,
The operational reliability and economy of power network are improved with this.
