Merlin Gerin Ringmaster range Indoor/outdoor medium voltage distribution 3.3 - 13.8kV

Merlin Gerin Ringmaster C - concentrated efficiency. Ringmaster, the first choice in medium voltage switchgear, incorporates new developments to meet the changing needs of the electrical supply industry. Covering a wide range of options with an indoor and outdoor IP54 design and ratings up to 13.8kV, 630A and 21kA, Ringmaster is suitable for all MV applications, from simple transformer protection to sectionalising with remote control. With the reassurance of quality engineering for extreme climates, Ringmaster has proved successful in markets around the world.

2

Flexibility and efficiency to meet your future needs. Ringmaster C is able to cater for customers’ future MV application needs. It has been designed with an easy motor retro-fit capability making it simple and cost-effective to add telecontrol and automation at a later date. The wide range of modular extensible and non-extensible switches, circuit breakers and metering units provide a comprehensive range of solutions to meet the varied requirements of customers.

Talus technology improves the quality of supply

Leading reliability and safety combined with low ownership costs. The Ringmaster range is based on over 12 years of established performance, proving both reliable and safe. Cost effective to maintain, it has easy access for testing and requires minimal maintenance.

Space saving design makes Ringmaster easy to install. Installation costs are further reduced because the robust Ringmaster can be used outdoor, in all climates.

Talus 200E technology provides the control and monitoring of networks from a remote central point. Integrating Talus 200E telecontrol cabinets into Ringmaster efficiently isolates network faults. Location of problems and re-configuration is completed with minimal downtime and without manual intervention.

A complete solution giving you the benefit of increased efficiency. Talus 200E is the key to implementing efficient, reliable and cost effective distribution systems. The compact Ringmaster offers additional benefits when used in conjunction with Talus 200E telecontrol cabinets.

Today’s situation MV distribution networks incur the largest single source of supply interruptions. The operation of the secondary network traditionally relies on manual operation where faults are reported to the utility by consumers or systems in the primary substation. The primary substation only indicates when an entire feeder is disconnected and not the fault location. To reconfigure a manually operated system is time consuming and requires physical inspection of the network. Talus 200E helps solve this, because it allows users to manage a distribution network from a remote central point. Talus 200E provides the necessary interface between control centres and the Ringmaster installation.

Talus 200E

Tomorrow’s solutions The Talus system monitors and controls the status of the equipment and communicates the information back to either the primary substations or control room. By using this remote operation, the fault location and network reconfiguration is completed with minimal down time and no manual operation. This improves the quality of supply and reduces network operating costs. Merlin Gerin offers the total solution for a one stop package by integrating Talus 200E within the distribution automation and management systems. This means that specifying is made simple, and there is only one source and one contact from initial ordering to after sales service for the complete system. Ringmaster telecontrol cabinets provide the means to improve the quality of supply in addition to reducing the network operating costs.

Integrated system solutions. Ringmaster range of switchgear, Talus 200E MV telecontrol interfaces and Milenium 8100/8200 distribution automation systems provide the total solution for distribution automation. Milenium 8100/8200 network control centre The network control centre is the computer system used to centrally monitor and control the physical distribution network. The real time information received from the telecontrol interfaces would be collected and processed at the control centre. The Milenium 8100/8200 distribution automation system is the way in which this physical network is modelled, for example, the system models both the network devices and the interconnection between the devices.

Telecommunication medium The telecommunications medium must provide a reliable and efficient link for the information to flow between the Talus 200E telecontrol interface and the Milenium 8100/8200 distribution automation system. Since there is not a single global solution to telecommunications, the equipment is flexible to communicate over different mediums including: ■ Licensed and unlicensed radio MPT1411 and MPT1329 ■ Mobile data network - PAKNET Vodafone Data Network ■ PSTN - dial up and leased line

Switchgear and protection

Ringmaster offers protection to meet cost and high levels of service criteria. Two types of protection systems are available: ■ Time Fuse Links - CT operated trip coils with provision for Time Fuse Links (TFL). ■ VIP Protection relays - self-powered IDMT, DT overcurrent and earthfault relays.

TFL protection An effective low cost option without compromising reliability.

Principle of operation The current transformer feeds a trip coil that is normally shunted by a time fuse link. In the event of a fault the fuse ruptures, diverting all the fault current through the trip coil, tripping the breaker. A residually connected trip coil provides instantaneous earth fault protection.

CT operated trip coils (with TFL) provides phase overcurrent and earth fault inverse time protection, the characteristic being given by a Time Fuse Link (TFL). This option is suitable for transformer protection up to 1600kVA.

VIP Protection relays self-powered reliability VIP 300 - the leading protection relay providing a wide range of selectivity and quality of supply. The VIP 300 is a three phase overcurrent and earth fault protection device, providing protection for networks and equipment. Being an integral part of the highly successful Ringmaster range, its main function is to detect phase and earth faults within the network and to trip the circuit breaker.

Flexibility The relay provides for a wide range of protection settings for most applications. The IDMT characteristics employed for both the overcurrent and earth fault elements can be easily adjusted to provide discrimination with upstream MV and downstream LV protective devices. Fast power - up of the VIP 300 also provides immediate protection and can detect faults instructing the CB to trip in less than 40ms.

Reliability The relay has a self monitoring device and diagnostic routine which constantly checks the operation of the relay automatically.

The VIP 300 protection relay is a self powered microprocessor based device which requires no external DC power source or batteries, making it the ideal solution for location in remote areas where auxiliary supplies are not readily available.

Ease of use VIP 300 has improved operation and control with the relay settings being clearly displayed on the front panel. Manual reset flags show separate ‘tripped on fault’ for either phase or earth fault conditions.

Testing The VAP 6 hand held test unit, is available to provide a simple check of the integrity of the relay and can also be used to perform trip tests on the circuit breaker. The circuit breaker “trip inhibit” facility allows the relay to be tested without tripping the circuit breaker. Secondary injection can be carried out using conventional test equipment.

VIP 30 and VIP 35 relays - with self-powered reliability The VIP 30 and VIP 35 are self-powered devices, requiring no external DC power source or batteries. They are designed for use in distribution networks providing protection for transformers.

VIP 30 provides protection against phase-to-phase faults. VIP 30

VIP 35 provides protection against phase-to phase faults and earth faults.

VIP 35

VIP 10 - for directional earth fault current flow indication A solid state bi-directional earth fault passage indicator to be used with Ringmaster. Its main application is to identify the faulty section of cable in a closed ring MV distribution network, by indicating the direction of the earth fault current flow.

VIP 10 is for conventional ring main units, such as Ringmaster RN2c when used between unit/differential protected substations.

VIP 10

VAP 3 - protection control This device is mainly used with VIP 300 and Ringmaster sectionalising circuit breakers. It provides tripped on fault indication and allows the protection to be enabled and disabled through Talus 200E telecontrol cabinets, eliminating the need for manually disabling the relay settings.
