Ultra-early-stage Partial Discharge Diagnosis and Monitoring System - Large Shopping Mall
The well-known shopping mall building in Taipei City has high-voltage equipment including high and low-voltage switchboards, power switch panels, capacitors, transformers, and generator systems, etc. of various specifications and brands. Since they had been used for a long time, the “Power Guard Ultra-early-stage Partial Discharge Diagnosis and Monitoring System” was first used to do complete testing of all high-voltage equipment, and only those found with abnormalities were eliminated/replaced. There is no need to replace all high-voltage equipment, and this saves significant costs.
Once obsolete high-voltage equipment elimination/replacement was completed, the “Power Guard Ultra-early-stage Once obsolete high-voltage equipment elimination/replacement was completed, the “Power Guard Ultra-early-stage Partial Discharge Diagnosis and Monitoring System” was introduced comprehensively. Therefore, as soon as partial discharge occurred, it could be detected and determined correctly in real time and appropriate maintenance and care, inspection/repairing, or replacement can begin upon occurrence of major abnormalities, which will not only lower the cost of maintenance and cost but also significantly reduce the risk of public security accidents and fires triggered by high-voltage equipment and losses associated with power failure.
Customer demand:
-
esting of existing equipment and elimination/replacement of only abnormal equipment
-
Effective detection as soon as partial discharge occurs
-
Determination of the type and severity of partial discharge
-
Harsh working conditions (excessive and complex dynamic electric wave statics)
-
Recording of historical vibration data required to be the comparison basis
-
Easy-to-learn and easy-to-operate user interface
Key issues:
-
There are many dynamic electric wave statics with complex compositions; they can hardly be addressed with conditional threshold valves
-
Partial discharge changes with the electricity consumption status, climate, and insulation quality of the equipment itself
-
It is difficult to detect partial discharge during the early stage; the system needs to be sufficiently sensitive and does not involve reporting errors
-
It is impossible to detect equipment of varying brands and specifications in the same way
Solution:
-
Digital full-frequency electro-magnetic wave sensor plus Edge AI Host
-
Real-time PRPD to identify the type of partial discharge
-
AI dynamic statics and noise-canceling to reduce the error rate
-
Ultra-long 100M antenna connector for easy installation
Benefits to Be Fulfilled:
-
Reduced disasters and losses caused by partial discharge
-
Effective control over the fit state of high-voltage equipment
-
Possible inspection/servicing or elimination/replacement of equipment with serious partial discharge
-
Extended life span of existing high-voltage equipment
-
Easy to reflect upon and track partial discharge
