Partial Discharge Detection Kit

 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.

PD asset management capabilities: allows you to RFID tag all your electrical assets. The RFID tag (Radio Frequency Identification) can be attached to your specific MV and HV electrical assets and then use our Intelligent Patrol methodology.

This feature and method allows Predictive Maintenance information such as Asset ID #, substation name, and electrical asset name, current and historical Insulation condition values to be electronically scanned, stored and saved. It provides a new test number each time a new test is conducted on the electrical asset, produces reports and data sheets as well as housing this information on a windows based platform.
