Description
VLF Sine 62 kV, with integrated tan delta which is a compact, robust, and portable high-performance test and diagnostic system for medium voltage cables.The VLF Sine 62 kV tester is a multifunctional tool. Not only can it perform VLF and DC testing, but it can also perform sheath testing and sheath fault pinpointing. Moreover, the optional internal tan delta expands the system to assess both cable integrity and condition. The system can also be used as a voltage source for the optional and lightest on the market available PD attachment, the PDS 62-SIN. Via this it can be expanded to a universal testing and diagnostic system enabling withstand testing, tan delta diagnosis and partial discharge diagnosis. 62 kV tester is a multifunctional tool: apart from VLF and DC testing, it can also perform sheath testing and sheath fault pinpointing
Overview of VLF Sinus 62 kVÂ
- Performs cable withstand testing, cable diagnosis and sheath fault pinpointing
- Smallest and lightest unit on the market in its class
- Automatic result interpretation as per latest IEEE 400.2 standard
- Easy field operation with no need for external computer
PDS 62 Portable PD detection and localization system Features
- Partial discharge diagnostics with VLF sinusoidal voltage up to 62kVpeak
- With 14.5 kg – the lightest PD measuring unit on the market
- Real-time data evaluation and display of results, no post processing needed
- General and localized Phase Resolved PD pattern (PRPD) display for defect type recognition
-
PD measurement acc. to IEC 60270
For the first time, it has become possible to immediately locate faults in underground cables during the actual PD measurement. The PDS 62-SIN has been designed for all Megger VLF Sinusoidal testers up to 62kVpeak.PD detector software will support the user with the data evaluation by means of so called Phase Resolved Partial Discharge (PRPD) patterns. With help from these PRPD patterns the user is able to distinct between different types of PD defects, such as corona or internal PD. This is of major importance for partial discharges located at terminations; corona discharges are not problematic,whereas internal PD would.
