Acoustic Monitoring Systems-Leaks, PD, Vibration
Acoustic Emission Diagnostic and Monitoring of Power Transformers
Power transformers account for the largest portion of capital investment in transmission and distribution substations. Failure of a single power transformer carries a multimillion-dollar impact with a build or replacement timeline of18-24 months. Yet 53 percent of transformer failures are preventable. But what if there was a way to protect that substantial investment while safeguarding…
SUBSTATION ACOUSTIC EMISSION WIRELESS SENSORS
APPLICATIONS ON POWER EQUIPMENT Acoustic Emission (AE) Wireless Sensor Nodes This system together with its sensors is applicable to the monitoring of medium and high voltage equipment such as transformers, circuit breakers, CT’s, VT’s, GIS, bus bars, etc. The main purpose of having Power Circuit Breakers on the substations is to protect the equipment from…
SteamPAC™ Hand-held Valve Leak Detection System
SteamPAC™ Surveys Steam Valves and Traps While In Service Identifying Valve Leaks! This Handheld leak detection system identifies and quantifies through-valve loss of normally-closed steam valves for power generation. “In 2007 a major mid-west utility with a 690-MW unit, found and repaired leaking cycle valves with SteamPAC™. This improved the condenser’s back-pressure allowing them to realize…
Pocket AE-Power™
Screening Tool for PD/Particle Problems in GIS and for PD/Gassing Problems in Power Transformers The Pocket AE Acoustic Emission (AE) system is a computerized hand-held instrument for AE testing and leak detection applications. Due to its portable nature and full AE features and functions capabilities, this system can be used in any remote, short…
PowerPAC™: Acoustic Emission Testing Technology Packages
PowerPAC™ is a Technology Package for detecting, locating and assessing not only partial discharge in power transformers but also thermal faults by utilizing Acoustic Emission technology. Transformers are instrumented with AE sensors covering both the tank and the LTC compartment (if one is present). In addition, other sensors (used to monitor pump current, fan current, load…
