MiCOM P54x is designed for high performance overhead line and cable applications, it interfaces readily with the longitudinal (end to end) communications channels and has optional distance backup protection. Models available: MiCOM P541, MiCOM P542, MiCOM P543, MiCOM P544, MiCOM P545, MiCOM P546

The MiCOM P541-P546 series provides high-speed current differential unit protection. The P54x is designed for all overhead line and cable applications, as it interfaces readily with the longitudinal (end-end)communications channel between line terminals. The interface options support direct fibre optic, or multiplexed digital links.

Optimum selectivity is assured, as the scheme measures the currents entering and leaving the protected plant item. Instantaneous tripping results for an internal fault, with stability for any out-of-zone fault. Tripping uses a proven characteristic comparing differential current with through current, for ease of testing. Phase differential elements of this type offer consistent detection of solid and resistive faults, with optimum faulted phase selection, tripping, and indication.

A full range of back-up protection is integrated. This enhances the dependability of the protection, as hot-standby elements (such as distance zones and overcurrent) can be brought into service whenever a signalling channel outage may occur.

P543 P546 devices offer resident subcycle distance protection, to complement the powerful suite of main and backup protection already proven within the family. Full scheme, five zone distance protection is adopted from the class-leading MiCOM P443.

The P54x becomes the standard in all HV, EHV and UHV line protection applications, duplicated where dual redundant main protection is demanded. Set any combination of differential, distance, overcurrent, and reclosing, depending on the site needs.

One universal relay type instead of two or more discrete models means reduced spares holding, less training, and lower cost.

Breaker control and monitoring application
The MiCOM P544 & P546 is suitable for the complex installation and feeders controlled by two circuit breakers such as the breaker-and-a-half configurations. While MiCOM P543 & P545 are suitable for feeders controlled by a single circuit breaker.

The MiCOM Agile P541 & P542 series provide high speed current differential unit protection. They are designed for overhead line and cable applications, interfacing readily with the longitudinal (end-end) communications channel between line terminals. The interface options support direct fiber optic or multiplexed digital links.

MULTI-ANALYSER SF6

For verification of several parameters in one operation

3-038R-R...
MULTI-ANALYSER SF6 with return system

This multi-functional device allows the determination of up to six quality parameters with only one measurement:

• SF6 concentration (%)
• Moisture concentration
• SO2 concentration (ppmv)
• Option: HF concentration (ppmv)
• Option: CO concentration (ppmv)
• Option: H2S concentration (ppmv)

The Multi-Analyser SF6 is a battery-operated, compact, user- and maintenance-friendly device which guarantees high measuring accuracy. The unit allows di­fferent kinds of measurements and treatment of the measured gas in one of the following ways:

» The measured gas can be stored in an internal storage vessel and pumped back into the gas compartment (up to 10 bar pe)
» For measurements on cylinders, vessels or gas compartments with higher pressure (max. inlet pressure 35 bar pe)
a pressure reducer is not needed. If the gas should not be pumped back into the SF6 filled equipment, a cylinder can be connected directly to the outlet. It is not necessary to disconnect the device from the gas compartment, the vessel or cylinder with the higher pressure.
» An external gas collecting bag can be connected allowing continuous measurements (inlet pressure max. 35 bar pe) without pumping the gas back. The external bag can be emptied by using the Multi-Analyser SF6, a service cart or compressor unit.

• No gas emissions during the measuring process
• Modular interchangeability of all sensors
• Operation with or without battery (external power supply)
• Exchangeable battery (replacement and separate shipping is possible)
• Easy and user-friendly menu navigation via high quality 7“ capacitive colour touch screen
• Optional remote control

• Automatic interval measurement is possible
• USB and LAN connection
• Storage of up to 500 measurement results with name
• Adjustable user languages: DE, EN, FR, ES, IT, PT, CZ, PL, CN, JPN, RUS
• Compact design, easy handling and transportation (installed in a trolley case)

In practice, the device covers two important functions. The integrated vacuum pump is the core component of the device. This vacuum pump evacuates the air down to < 1 mbar so that no air/gas mixture is produced during the subsequent filling process. The well proven DILO coupling principle ensures safe handling without emission.

Using the 3-001-4-R022 version the filling weight can be registered comfortably by means of a weighing scale. The weight is indicated on the illuminated display which switches off automatically if the scales are not used for a certain time. Thanks to the tare function high precision quantification of gas inputs and outputs is possible.

Other features:

• Stable frame
• Accuracy of the weighing scales ±20 g (±50 g only for 3-001-4-R122), 10 g increments
• Integrated serial interface for data exchange or monitoring
• No emissions by self-closing couplings
• Available as accessories for the world‘s most commonly used bottle connections
• Hose reel
• Couplings can be exchanged without any gas loss
• Primary gauge NG63, class 1.6 / Secondary gauge NG100, class 1.0

SMALL SERVICE CART

For efficient SF6 gas handling on small gas compartments

B143R11

The compact and mobile SF6 gas reclaimer meets all requirements for efficient gas handling in the medium voltage range. Compact design and ergonomic aspects have been the main focus for its construction.

The maintenance unit allows gas recovery down to a final vacuum of < 5 mbar and keeps pace with large devices. All necessary functions are integrated including gas purification via dry filter and particle filters as well as gas storage in liquid form. Operation of the device via colour touch panel sets a new standard in this device category as icons are clearly displayed for a quick overview of the entire process.

Equipped with four solid tired wheels, the SF6 recovery unit can be conveniently moved on uneven and gravel ground. The integrated tool box keeps hoses and accessories tidy. Thus the B143R11 is a compact, efficient and user-friendly device complying with the requirements in the MV field.

Other features:

• Device for liquid storage of SF6 gas
• SF6 gas recovery down to < 5 mbar
• Semi-automatic control and 3.5" colour touch panel
• DN20 coupling for recovery, evacuation and filling operations
• Digital weighing scales for SF6 bottles
• Residual gas recovery down to 5 mbar during filter change
• Reduction to transport pressure as integrated special function 

MEGA SERIES

Maintenance unit for large and extra-large gas compartments

L170R01

The L170 maintenance unit has been developed as entry-level model of the Mega Series for the gas handling on large gas compartments. Thanks to the state-of-the art control all functions run automatically and are displayed on a 10“ multi-touch screen. A new software with intuitive user navigation makes operation very easy and comfortable. This service cart can optionally be operated via smartphone, tablet or laptop.

Precondition for the construction of this series which allows SF6 gas recovery down to < 1 mbar was emission-free gas handling. When using the totally gastight DILO couplings and connecting systems emissions will have no chance! Short gas recovery and evacuating times are obtained by using a coupling DN40.

The L170 series is available with a second DN20 connecting coupling (as option) so that two work steps can be carried out simultaneously. Thus it is possible to evacuate air from a gas compartment while filling SF6 at the same time or recovering gas from another gas compartment. Multitasking in practice.

Other features:

• Devices for liquid storage of SF6 gas
• SF6 gas recovery down to < 1 mbar
• Automatic control and high quality capacitive 10" multi-touch screen
• Optional remote control via mobile devices
• Reversing switch for direction of rotation
• Digital weighing scales for SF6 cylinders
• Residual gas recovery down to 1 mbar during filter change
• Reduction to transport pressure as integrated special function
• All versions are available with tanks which can be assembled under the device with CE marking also available with SQL and ASME approval
