Other DetailsABB offers a complete solution for 12/24 kV distribution networks. This consists of Safe Ring, a Ring Main Unit (RMU) that can be supplied in various configurations and Safe Plus, a compact switch gear with unique flexibility. Safe Plus offers extendible and fully / semi modular configuration possibilities. Both the units have identical user interfaces. Safe Ring / Safe Plus are delivered as a completely sealed system with a stainless steel tank containing all the live parts and the switching equipment. Constant atmospheric conditions in the sealed tank ensures a high level of reliability, safety and a virtually maintenance-free system. As an option in Safe Plus, an external busbar can be provided to enable a completely modular configuration. Safe Ring and Safe Plus can also be fitted with a remote control and monitoring unit and are suitable for both indoor and outdoor applications.

Other Details

• RVC has become synonymous with automatic capacitor bank controller in many markets worldwide thanks to its distinct design, ease of use, reliability and versatile functions.
• Thanks to the user interface upgrade with graphical icons, it is possible to commission the RVC without a manual. A slimmer casing requires less space in the capacitor bank panel.
• The RVC is an easy-to-install, easy to use, smarter power factor con- troller and an ideal companion of your automatic capacitor banks.

Powerful Features

• Common range for a broad network voltages from 100V to 440V.
• Measurement and display of key parameters like voltage, current, power factor, THDV and THDI.
• Fully programmable switching sequence.
• 1A or 5A current input.
• Easy commissioning.
• Complete auto set-up (starting current-C/k, type of switching sequence, phase shift, special connections).
• Easy to use thanks to a user-friendly touchscreen interface and ease of access to parameters for manual setting.
• Highly efficient switching strategy combining integral, direct and circular switching thereby allowing:
• To control the cos in presence of rapidly varying loads,
• To reduce the number of switching,
• To avoid unnecessary intermediary switchings,
• To increase the lifetime of the capacitors and contractors.
• Suitable for hot environments due to maximum ambient temperature rating of 70°C.
• Not affected by harmonics.
• Overvoltage / undervoltage protection and protections against harmonic distortion (THDV).
• Alarm : an alarm contact is opened when any of these conditions are reached:
• The target cos Φ is not reached within 6 minutes after all outputs have been switched on,
• The internal temperature of the RVC rises above 85°C,
• Overvoltage / undervoltage limits are reached,
• The power supply is out of range,
• The THDV exceeds the limits.

Other Details
Power factor correction for both balanced and unbalanced loads:
In nowadays installation, unbalanced loads are becoming ubiquitous, especially in residential or commercial buildings. RVT addresses your power factor issues from both single phase loads (L-L or L-N) and three phase balanced/ unbalanced loads. RVT is capable of compensation to each phase individually or compensation to three phases globally. Another distinct feature of RVT is individual phase measurements and energy counting.

Complete three phase measurements

• Active power (kW) - 3ph/1ph
• Apparent power (kVA) -3ph/1ph
• Reactive power (kvA) -3ph/1ph
• Reactive power (kvA) to reach the target cos -3ph/1ph Voltage (V) -3ph/1ph
• Current (A) -3ph/1ph
• Cos -3ph/1ph
• Total Harmonic Distortion on Voltage/Current : THD V/I (%) Voltage/Current Harmonics : H2 up to H49 (%-spectrum)
• Touch Screen
• Ethernet connection
• USB connection
• Up to 8 Temperature alarm outputs
• Real time clock
• Hardware and software lock

Other DetailsAcross every market ABB's breakers occupy a leading position thanks to their proven reputation for reliability, performance and long life. CBs from ABB are available for original equipment manufacturers (OEM) to incorporate in their own installations or for use in repair, retrofit and upgrade projects.

Why ABB

• Full engineering and technical support
• Products tailored to meet the needs of your local market
• Short lead times
• Fast response

Other DetailsThese circuit breakers are of live tank design. The vacuum interrupters are housed in hollow porcelain insulators filled with SF6/Nitrogen gas at 0.5 bar above atmospheric pressure to safeguard against condensation. The operating mechanism is housed in a weather proof cabinet and is available in two versions:

• Magnetic Actuator Drive
• Spring Operated Mechanism

Why ABB?

• Porcelain clad construction suitable for outdoor applications
• Operating mechanism available in two options - spring drive or magnetic actuator drive
• Suitable for auto closure duty cycle of "O-0.3sec-CO-3min-CO" and "CO-15sec-CO"
• Simple installation - structure mounted with option of extension.

Other DetailsRETROFIT means the implementation of modern components (primary switching devices and digital protection/control technology) in the existing MV installation with following benefits.

• Cheaper than a complete replacement
• Short implementation time for replacement
• Minimum shutdown of the switchboard
• Remaining service life extension
• Improved operator protection
• Minimization of further maintenance costs
• Warranty on the conversion work
• Spare parts availability for long time

Principle of OperationA weigh belt feeder enables a continuous, controlled product flow. The bulk material is transported over a weighing section, placed in the feeder frame. The federate is calculated and the speed of the belt adjusted to maintain a constant feed rate.
If the purpose of the belt feeder is to register the throughput only, the speed of the belt remains constant and the mass flow and cumulative weight is registered.

ApplicationsWeigh Feeders are widely used in

• Coal feeding
• Steel plant
• Cement plant
• Chemicals & fertilizers
• Open mines
• Tobacco industry

Advantages of well maintained APFC system

• Avoid Power Factor Penalties. Most industrial processing facilities use a large quantity of induction motors to drive their pumps, conveyors, and other machinery in the plant.
• Reduced Demand Charges.
• Increased Load Carrying Capabilities in Existing Circuits.
• Improved Voltage.
• Reduced Power System Losses

Why ABB?

• More than 40 years in the market
• Perfected and developed technologies including all applications
• Continuous innovation,  research and development with focus on the customer
• More than 40, 000 dry-type transformers operating all around the globe
