MEGGER PDIX
Megger power diagnostic majorly offers solutions for Partial discharge measurement and monitoring. Megger PDIX also offers loss factor (LF/DF) measurement devices, fiber optic analog and digital signal transmission systems, high voltage test and control systems and cabinets, plus many other tools for high voltage diagnostic applications. Beside all these special products for quality control and life cycle assessment of insulation materials and components, PDIX also provides services, expertise, and training seminars in this special subject.
Partial Discharge can be measured and monitored on:-
- Rotating Machines
- GIS Systems
- Power Transformers
- Cables
Importance of Partial Discharge
- Earliest method to detect insulation degradation
- Predictive maintenance.
- Useful for trending of condition of critical assets
- Allows for advanced diagnostics of insulation (i.e., type and location of fault)
- Partial Discharge Testing is part of the quality assurance process defined by valid standards for FAT
VAISALA
Vaisala is well known for a broad range of power and energy industry probes, monitors, process control and services that are used in power transformer condition monitoring, lighting detection, and weather station applications. Vaisala Power transformer monitoring solutions help in predictive maintenance and prevention of unplanned outages.
The main equipment for this include:-
- Online Dissolve Gas Analysis equipment; the OPT100 and the MHT410
- Moisture and temperature meter
- Dew point meter
Importance of Online Monitoring
- Most internal faults detected at early phase
- More reliable gas trending
- Incidents detected that might go un-noticed with sampling
- Safer use of transformer end-of-life phase
- Faults originated from manufacturing, transportation or installation revealed
GE GRID SOLUTIONS
GE Grid Solutions are committed to combining knowledge and technology to address the most difficult power system problems, hastening the world’s shift to a more dependable, greener grid. GE has partnered with Amotech Africa as a Value-added reseller in East Africa and products covered under this partnership include:
1. Monitoring and Diagnostics
Solutions under monitoring and diagnostics include Portable and online Dissolved Gas Analysis solutions, Bushing monitor and partial discharge monitor and Circuit breaker monitoring systems. It is important to monitor the performance or our assets for electric utilities and industrial customers as this guarantees operational efficiencies, reliability and helps to cut the operational costs. Some of the benefits of M&D include:
- It reduces the risk of catastrophic failure
- Helps to avoid unplanned outages
- Reduced maintenance costs
- Stretch asset capability
2. Protection & Control
Under protection and control we have, Protection relays, Bay Controllers, Digital Fault recorders, Merging units, RTU and SCADA systems among other solutions. The main outstanding features of GE Multilin and Micom Agile relays include:
- Powerful hardware platform
The relays have powerful processing feature, are able to withstand hash environmental conditions.
The relays have a high sampling rate with fast protection pass and a deterministic protection and logic.
- Easy to integrate to existing systems
The relays are compact with high I/O density and communication protocols i.e IEC 61850, IEC103, Modbus and DNP3.0.
- Asset Monitoring and management
GE relays are best in class self-supervision. They are also able to do trip circuit supervision, monitor the CT, VT, circuit breaker and the DC supply. The relays can store events, faults and disturbance records.
3. Networking and Communication Solutions
Under this we have:
- Network switches
- RTU’s
- Gateways
- GPS clocks
- Software’s and general Substation Automation Systems
We are also qualified to undertake projects, offer services and support on GE products and systems.
