NH 00 | UPPER SOLUTION

The SBT is the feeder meter for NH 00 switches. It´s located on top of the fuse switch, as an extension of the BTVC.
The SBT is connected to the CT’s and voltage taps installed at the rear of the fuse switch.

TSA (ADVANCED SUPERVISION CARD NH 1/2/3)

TSA is a three phase feeder meter compatible with both upper and lower LV monitoring solutions. It calculates RMS values per second of the following variables:

• Voltage per phase
• Current per phase and calculated neutral current
• Imported / exported active, reactive and apparent power per phase and total
• Power factor per phase
• Phase presence
• Frequency
• Cumulative values of imported and exported energy
• Cumulative values of reactive energy in all four quadrants
• Temperature inside the card
• Voltage and current oscilography in case of an alarm

Moreover the card can generate the following alarms per phase:
blown fuse, over/under voltage,current overload, shortcircuit current.

TSA can communicate by DLMS / COSEM protocol on HDLC with the LV Edge Node, or by Modbus RTU. They are connected by a RS485 serial bus in daisychain format (maximum 24 feeder meters per bus).

Fuse monitoring unit for 3 phases system up to 690 V, compatible with NH 00 / NH 1/2/3 TRIVER fuse switches.

The Fuse Supervision Control unit has been developed specially for its application on vertical design fuse switches. It maintains all TRIVER features in terms of dielectric properties and withstand the usual temperature conditions in LV distribution installations.

It is available in electronical and electromechanical version.

A complete solution for current metering integrated in the standard fuse switches. It is offered totally integrated into the fuse switch, in the form of a compact and robust assembly, which means a saving of time in the arrangement for the final user.
The current transformer, integrated in the standard fuse switch doesn’t increase the total depth of the device.

Current-transformers are available in different current ratings (up to 600 A) adequate for NH 00 and NH 1/2/3 fuse switches. Secondary current available in 1 A and 5 A. Accuracy class (0,5 and 1) and burden from 1 VA – 7,5 VA.

Connections and cables lay out are made in a smart way to provide a completely protected solution for safe handling.

• 3 phase permanent metering set | This accessory can be installed in any standard fuse switch. The depth of the product increases 41 mm.

• Temporary metering set | Special current transformers in fuse shape design can be installed for temporary current metering.

• 3 phase permanent metering set with maximeter and 3 phase permanent metering set with digital panel meter | These supports can be fitted directly on the fuse switches, so the metering device can be close to the metering point and the cabling is simple and safe.
