Live Retrofit Supervisor is a new solution that allows live installation of LV advanced monitoring on any type of three pole fuse switches or circuit breakers with no interruption of the energy supply. The LRS is compatible with any type, country standard and brand of fuse switches, any type and brand of ciurcuit breakers and also compatible with old infrastructure.

This new product has the following features:

• Live installation
• Compatible with any LV Panel, brand and type of fuse switches and circuit breakers
•  Same electronic cards of our other solutions such us Smart Fuse Switches.
•  Same performance of our other supervisors, including measurements per line and phase
• Cabling concentrated in each line, no cable on the ground
• Flexible location of each component on the energy cables
• Fast installation
• The solution is compuesta by a feeder meter case, current transformers, voltage taps  and voltage cables.

For more information, please contact us using the form.

New the pole vertical fuse switches, with parking position and improved grounding connection.

• NH 1/2/3 size.
• Distance between busbars 185 mm.
• Rated operational current up to 630 A.
• Rated operational voltage up to 690 Vac.
• Handle with increased robustness
• Smart fuse switch. Includes the option of advanced supervision

The LV transformer supervisor allows the status of the LV transformer in the Secondary Substation to be monitored. Compatible with any type of transformer, it has a three-phase voltage input and one or two three-phase current inputs for measuring electrical parameters.

Equipped with several communication ports, it allows complete monitoring of the transformer’s electrical parameters, including temperature measurement in the advanced version of the device. Its easy and intuitive user interface allows to quickly check its correct installation and operation.

Applications

• Transformer supervisor in the LV output: monitoring up to 2 different outputs. For indoor or outdoor transformers (on a pole)
• Feeder supervisor in the Secondary Substation: LV panel supply feeder or LV outgoing feeder
• Monitoring of any intermediate element of the LV network: feeder pillar, main circuit breaker protection box…
• LV network remote monitoring. Device compatible with a 4G router
• Measurement of harmonics in voltage and current and THD (Total Harmonic Distortion), up to n=40 (*)
• Internal algorithm for estimating transformer oil temperature. This data can be used to know the transformer status, its overload level and its aging (*)

The CUMA 21 range of low voltage panels offers different types of incomings. Among the main options available are:

1. LBS | Load break switch
2. Three-pole vertical fuse switch:
   • BTVC (TRIVER+) 910/1000 A | Three-pole vertical fuse switch
   • BTVC-D 800/1260 A | Three-pole vertical double fuse switch
3. MCCB | Circuit Breaker
4. ICD | Integrated compact disconnector

Different combinations available depending on the selected components. Option to choose different outgoing options.

From 4 up to 12 three-pole vertical fuse switches (BTVC) NH 1/2/3 size or up to 24 outgoings NH 00 size (185 mm busbars).

POSSIBILITY OF EXTENSION

An extension module can be connected to the main panel if more outgoings are required on the right or on the left according to the client’s preference.
This option is available for the Load Break Switch and Circuit Breaker incoming connection models for both frame and enclosure.
The maximum number of outgoings that can be added by means of these extension modules is 12.

Depending on the type of connection, the range of CUMA 21 panels allows up to three different enclosures to be used: frame, closed frame or metallic enclosure. This versatility of the product favors the integration of supervision equuipment in the transformation center.

• Frame: possibility of mounting with any type of connection, either with a load break switch, with NH fuse switches, circuit breaker or integrated compact disconnector.
• Closed frame: possibility of assembly with a connection to a compact integrated compact disconnector (ICD).
• Metallic enclosure: allows assembly with any type of connection.
