Detail PMDT PDetector

PDetector is the ideal partner for condition-based maintenance programs. Online partial discharge testing is a method of inspecting the insulation of electric power systems while equipment remains energized and in service. PDetector incorporates all 5 types of online PD sensor technology. Information from multiple sensors gives PDetector the versatility to detect all types of PD in all types of substation apparatus. Furthermore, the exact type of PD activity can be determined using PRPS: void, corona, surface, particle, or floating electrode.

Applications:

Power Cables
Transformers
GIS
Switchgear
Substation Apparatus

Sensor Technology : Detection Bandwidth

Electromagnetic (EM)

TEV - Transient Earth Voltage (built-in to main handheld unit) 3MHz - 100MHz
UHF - Ultra High Frequency - 300MHz - 1.5GHz
HFCT - High Frequency Current Transformer 500kHz - 50MHz

Acoustic Sensors (AE)

Acoustic Contact - 20kHz- 300kHz
Airborne Ultrasonic - 40kHz

Phase Resolved Partial Discharge (PRPD) - PD activity produces both electromagnetic and acoustic emissions. PRPD mode will automatically relate the occurrence of the incoming signals to the power frequency 60Hz (or 50Hz). This gives the user the ability to instantly determine if PD is present.

Airbourne Acoustic

40kHz Ultrasonic

PD activity which is at or near the surface of an insulator will produce an ultrasonic and sometimes audible emission. Surface tracking and corona always produce airborne emissions. Other types of PD may also produce a detectable acoustic emissions. Three ultrasonic sensors are included in the kit. The range is from 20kHz to 80kHz with a center frequency of 40kHz. Surface tracking and corona are common types of PD on insulators and bushings. It can be easily detected and confirmed using the airborne ultrasonic dish.

Software - Data Managment

PC Software is included. Enables you to build a network tree which includes all of the assets which are periodically tested. Each test file is stored and trended.

Intelligent PD Recognition Software
Trending - Programmable warnings and alarms
CSV Data Export to other asset management software

RFID - Radio Frequency Identification - Small RFID tags
can be used to automatically associate test data with specific assets. Automated Data Entry
Intelligent Patrol - Engineers can create a procedure with all test points in a list. The test point is selected on the list and the measurement data is stored and associate with the test point.
