Omicron MPD 800 | The Future of Partial Discharge Testing

Partial Discharge Measurement & Analysis for Power Cables

• uploaded by Chris Dodds | Thorne & Derrick Sales Marketing Manager 

Omicron MPD 800

MPD 800 universal partial discharge (PD) measurement and analysis system, the next generation of the widely-used and innovative MPD PD testing technology from OMICRON.

Advanced hardware and software features ensure highly-sensitive single- or multi-channel PD measurements for reliable, industry-standard PD testing on power transformers, rotating electrical machines (motors and generators), power cables, instrument transformers, switchgear, industrial drives and electrical components.

The configurable, multi-language MPD 800 software allows you to select only the PD measurement and analysis features you need for specific PD tests and individualised reporting. Powerful noise suppression and PD source separation techniques ensure reliable PD analysis in areas with high levels of interference.

The MPD 800 PD testing system accurately detects and localizes insulation defects and helps you to assess the risk of failure in electrical equipment during research and development, factory testing, site acceptance testing (commissioning), as well as in-service troubleshooting for effective maintenance planning.

“The MPD software guides you through the entire PD measurement process on power cables, and it provides you with detailed analysis and individualized reporting.”

Meets industry standards. The MPD 800 measures partial discharge in compliance with the IEC 60270 standard to ensure the reliable detection of PD activity in high-voltage power cables.

Reliable noise filtering. The MPD 800 provides you with a free choice of measurement frequency and bandwidths to maximize measurement sensitivity in environments with high interference.

Advanced analysis tools. MPD 800 uses advanced graphical tools, such as 3PARD (3-Phase Amplitude Relation Diagram), to separate multiple partial discharge sources for reliable fault detection.

PFISTERER TENSOREX C+ | The Patented Spring Automatic Tensioning System for Rail Systems

PFISTERER TENSOREX C+

PFISTERER TENSOREX C+

Automatic Tensioning System for Rail Systems

• uploaded by Chris Dodds | Thorne & Derrick Sales & Marketing Manager

PFISTERER TENSOREX C+ is an automatic tensioning system that uses the force of a coil spring to constantly tension the railway catenary and/or bearer cable.

The TENSOREX C+ is a patented spring automatic tensioning system which has been installed on many worldwide prestigious rail and tramway systems. It therefore effectively compensates the expansion caused by fluctuating daytime and night-time temperatures as well as the change in the seasons while keeping the tension at a constant level.

Applications

• For railways and tramways
• Best solution for portals, tunnels and platforms
• Inner-city installations where low visual impact is requested

Facts

• Units Sold: 14,000+ (Asia, Africa, Australasia, Europe, North and South America)
• Compensating Length: 450-1100 mm
• Line Tension Force: 7.5-40 kN

PFISTERER TENSOREX C+

PFISTERER TENSOREX C+ Advantages:

Highest reliability:
Every TENSOREX C+ unit is tested before shipping to the customer

Compact design:
Easy handling and transportation
Esthetical solution for inner-city installations

Fast installation
Delivered ready to install, no assembly required, no weights have to be installed

No tensioning weights required:
Vandal resistant
Free space on the mast base – escape routes are not blocked

Maintenance-free

High precision
Constant tightening force over the entire regulation range
Fast and precise response – very small traction force hysteresis

Purely mechanical system
Requires no additional power supply. No influences due to temperature changes

Reduced risk of vandalism / theft

Low impact aesthetics

Suitable for tunnels / areas of limited space

Mounting solutions available for all applications

Reusable in the event of wire failures

How it Works

By means of a support cable, TENSOREX C+ exerts a constant tension on the contact wire, regardless of any changes in length due to temperature. The special spiral spring is firmly connected to two cams on the same shaft. The degree of rotation of the shaft results in a linear variable torque/moment, which is compensated for by the combination with the variable radius of the cam.

This produces a constant pulling force over the entire device working range.

PFISTERER TENSOREX C+ | How it works?

^FContact wire = f (M/r) = const.

^FContact wire >> Force on contact line
^MSpring >> Torque/moment applied by spring (variable on linear basis)
^rPulley >> Radius of cam (variable)
lWork >> Device working range correspond to variable pulley profile length

What are the different types of Partial Discharge?

Partial Discharge

Neil Davies

Partial Discharge (PD) can be classified into 3 main types:

Internal Partial Discharge, occurring inside insulation

Surface Partial Discharge, tracking across insulation

Corona Partial Discharge, from a sharp electrode into gas

Internal PD is the silent defect where there will be no sound, smell or visual indication of a problem prior to failure. If you witness the aftermath of a compound insulated cable box failure, you will see how the build-up of pressure can lead to a very disruptive and dangerous explosion.

Surface PD occurs across the surface of insulation. When alternative materials to porcelain started to be introduced into switchgear and dry cable terminations started being widely introduced, some critical aspects of design and installation were not fully appreciated. This led to a spike in failure rates due to surface PD. When developed, it will produce the crackling and ozone smell.

Corona PD is what we often hear in outdoor switchyards, particularly when humid. Corona at sharp points in switchyards isn’t usually detrimental. However, if corona activity occurs inside enclosed chambers and there is no airflow to remove chemical reactions, then it can lead to the onset of surface PD and problems.
