The first self-testing obstacle warning light
The new range of TWINY obstacle warning lights is made of a master and a slave industrial beacons. The "slave" is automatically working as soon as the "master" is down. This design is securing the obstacle beaconing, since the system will be permanently operational. The Twiny range also includes a dimmer switch which will automatically switch on and off the lights during day and night time.
Furthermore, the TWINY range has a unique and specific self testing device, working daily or on request according to customer specifications. The test procedure check the two beacons conditions. If ever one of the light test is negative, a defect contact will report the information. The testing procedure is visible from the ground (no need to reach the beacons to start or witness the test).
Three types of low intensity obstacle warning lights are available within the TWINY range: the BA10 incandescent lights, the LED BA15 lights as well as the Neon BA20 and BA30 types.

Even small overvoltages can disable sensitive electronic equipment, professional computer networks and computer-controlled professional production systems in fractions of a second. For protection against overvoltages which can result from lightning or switching processes in electrical supply networks, OBO offers a wide range of surge and lightning arresters for the German and international markets. These include not only devices to protect AC networks of various voltage professional levels, but also special systems for data lines and telecommunication devices, and protective modules for process measurement and control systems.
With the new LightningControllern, OBO presents innovative over voltage protection systems with patented multi-carbon technology in the new VBS catalogue. The first modular spark gap for perfect integration into distribution systems. The great advantage of the new units is that they have a fully encapsulated professional housing. This means no more arcing! This eliminates the risk of fires in the distribution bin due to sparking.
The OBO range of systems for external and internal lightning protection is also complete. All components have passed the tests imposed by the Lightning Protection and EMC Technology Centre in Menden and have the corresponding test marks and certificates. |

| The quarter wave stub devices feature best in class performance specifications, including bi-directional protection, low VSWR, normal and reverse polarity, high RF power and ultra low let through(5V). Using robust materials in construction the maintenance free quarter wave serier is ruggedized, weatherproof to IP68 standard. |

Überspannungschutzmodule/Bremschopper
Those often also as Bremschopper designated units are built into the current supply, and short circuit with the exceeding of a certain voltage level the lines over a resistance. The surplus energy is dissipated by this procedure as warmth.

The voltage protector relay REU 610 is part of the RE_ 610 series of numerical relays for the protection and supervision of utility substations, and industrial switchgear and equipment.
The voltage protection relay is primary designed for the overvoltage protection of power system components, such as busbars, feeders, power transformers and capacitor manufacturer batteries. The relay is also used for general power system earth-fault supervision. Further, the relay can be used for undervoltage protection of motors and overvoltage protection of capacitor batteries, for initialization of automatic busbar changeover, and for disconnecting small power units from the network in cases of network disturbance.
The voltage protection relay REU 610 supports a wide range of standard communication protocols, among them the IEC 61850, IEC 60870-5-103, Modbus, Profibus and DNP. |

SIPROTEC 7RW600 is a numerical, multifunction relay for connection to voltage transformers. It can be used in distribution systems, on transformers and for electrical machines. If it detects any deviation from the permitted voltage, frequency or overexcitation values, it responds according to the values set.
SIPROTEC 7RW600 can be used for the purposes of system decoupling and for load shedding if ever there is a risk of a system collapse as a result of inadmissibly large frequency drops. Voltage and frequency thresholds can also be monitored.
This voltage, frequency and overexcitation relay can be used to protect industrial generators and transformers in the event of defective voltage control, of defective frequency control, or of full load rejection, or furthermore islanding generation systems. |

The A-ISOMETER® of the IR420 series is designed to monitor the insulation resistance of AC control circuits (IT systems) 0...300 V. If the systems to be monitored include DC components, such as switched-mode industrial power supplies or solenoid valves, the display and operating characteristics may be affected.
The display and response values apply to pure AC systems. An external supply voltage allows de-energized systems to be monitored too.
