MV Circuit Breaker Retrofit
RETROFIT AND UPGRADE OF MV SWITCHGEAR (CIRCUIT BREAKER)
The retrofit in medium voltage systems is a main stream activity of PTP from the creation of the company. To date, our team has successfully completed many projects in this segment, earning the company’s place and establishment on the market as a reliable and preferred partner.
All medium voltage equipment parts can be divided into several groups by depletion rate:
- Fixed parts: panel metal-clad, current and voltage transformer, isolators, buses and other. It is practicable not reduced category (except transformers)
- Moving parts: withdrawable elements, load break switches, high voltage and earthing disconnect operated switches are slightly modified elements
- Control circuit: traditional relaying and arc protection system, measuring instrument and signaling devices are mostly obsolete but still in use
- Switching Devices: power circuit breakers and contactors. This category is ages resulting on availability and technology properties of medium voltage switchgear. Minimal oil, electromagnetic and first use vacuum circuit-breakers are still in operation today
RETROFIT OF MEDIUM VOLTAGE SWITCHGEAR
PTP has the technical potential, the know-how and the experience to retrofit and to modernize various types of medium voltage switchgear.
THE RETROFIT PROCESS INCLUDES
Preparation of design project, refurbishment of circuit breaker’s truck, new support structure for the circuit breaker, instrument transformers etc.; Delivery and exchange of minimum oil or air blown type of breaker with vacuum or SF6 one according to customer preferences (ABB, Siemens, Schneider or else), instrument transformers, surge arrestors etc.; The new equipment is manufactured and tested at the factory and delivered to site by PTP ready for installation. This means that the existing switchgear can be kept in operation right up until the change-over, minimizing potential delays and production downtime.
ADVANTAGES OF SWITCHGEAR RETROFIT
- Increased reliability and safety during operation.
- Cost saving effect – the price of retrofit is significantly lower, compared to the investment for a new panel and also saves maintenance costs.
- Extending the service life of the panels with some 20-25 years.
- Easy upgrade of the equipment to a level for application of a new SCADA system.
PTP performs a retrofit of the various types of switchgear panels that have many years of operation in MENA Region, such as: Del ALSTOM, BBC, AEG, MAGRINI, ECA ALSTOM, CALOR EMAG, FUJI, Merlin Gerin FG2, HITACHI, 3AC SIEMENS and more
