MODEM GSM-4

GSM-4 protection relay remote control modem

M-GSM4 modems enable the implementation of remote control of Thytronic protection relays via GSM/GPRS/LTE mobile network up to and including 4G technology. Specifically, in combination with NV10P protection relay,they enable control of the opening and closing of interface devices installed via digital I/Os. Modem GMS-4 can be installed on photovoltaic and wind renewable generation systems having a total rated power greater than or equal to 100 kW, in compliance with the provisions contained in Annex M of CEI 0-16 Standard ed. 09-2014, CEI 0-16 Standard ed. 12-2014 V1, Resolution 421/2014/R/EEL 07-8-2014 and Annex A72 8-2014 and subsequent editions.

NV10P

The Thytronic NV10P protection relay, compliant with CEI-016 standards, can be typically used in HV, MV, and LV distribution systems, on transformers or for electric machines. It can be used for system decoupling, load shedding, and loss of main protection. 

Features of the NV10P Interface Protection Relay


The Thytronic NV10P interface protection relay has various functions to ensure reliable and precise protection in electrical systems. It fulfills functions of monitoring over- and undervoltage, measures residual overvoltage, negative sequence overvoltage, and frequency, both minimum and maximum, including frequency rate of change. This relay ensures the detection of circuit breaker failure and accurate supervision of the trip circuit, providing protection in compliance with CEI 0-16 standards. For communication functions, it is equipped with a type B USB port to facilitate connection and configuration via the ThyVisor software.

In combination with the NV10P relay, as an alternative to 
traditional voltage
transformers and insulators with capacitor divider, , V-Sensor can be installed in Medium Voltage Electric Panels for phase voltage measurement. These devices include the functions of:
  • Electronic Voltage Transformer
  • Capacitive divider for voltage presence lamps 
  • Insulator.
The sensor is offered in a single model suitable for installations with nominal voltage 10...24 kV and does not require the installation of  anti-ferroresonance resistors. 
Furthermore, for the remote control of the relay, it is possible to install the M-GSM4 modem with mobile GSM technology up to and including 4G, GPRS, and LTE, which allows for the command of opening and closing of the interface devices installed on generation plants with a total nominal power ≥ 100 kW.

Moreover, in plants where automatic reclosing (ARF) is active, by connecting the M-GSM4 Thytronic modem to the NV10P protection relay via ThyBus, the interventions for modification on the plant are minimized.
