20Hz Injection Kit Monitoring System
-
Signals & Systems India Private Limited
The Display used to monitor the 20Hz and 50Hz current passing through NGT transformer. This could help to monitor the stator earth fault and could record the current every minute. The current shall be displayed in milliamps for both 20Hz and 50Hz. If an earth fault occurs in the generator star point, the 20 Hz voltage drives a current through the fault resistance. The current can be measured using clamp-on CT which would be clamped between load resistor and NGT. It gives an indication of the current values are lower or higher than the set threshold.

Three Phase Reference Standard Meter
-
Signals & Systems India Private Limited
The Three Phase Reference Standard Meter (TPRS-1107) is portable equipment from SANDS. The main objective of this device is to calibrate the errors in three-phase and single-phase energy meters i.e. the meter under test (MUT). The TPRS supports both static and electro-mechanical types of meters. It can also be used to compute the voltage, current, energy, power factor etc of the meter under test. It has an LCD display, an alphanumeric keypad that makes it easy for the user to operate the TPRS. It can be interfaced with the PC for data analysis. It has the capability of storing up to 8000 test results.

Automatic Meter Reading Unit
-
Signals & Systems India Private Limited
SANDS make of AMR Modem SAM-1101 is a smart electricity meter reading device that can be connected to any make of electronic energy meter by means of optical/ RS232 port, which is compliant to DLMS – IEC 62056-21 standard. The electricity meters measuring energy consumption can be located in either consumer premises or in distribution transformers. The modem draws its power from the meter terminal block and connects to the communication port of the meter. Thus this add-on energy meter reading system is non-intrusive and can be retrofitted easily to any meter. The Electricity Meter Reading device uses GSM/GPRS communication technology and has built-in intelligence to talk to the DLMS meter. AMR system is compatible with 4G network to push the power consumption-billing data, load survey data, and event data to a cloud-based server, with fallback options to 3G & 2G.

20Hz Generator
-
Signals & Systems India Private Limited
In order to implement a 100 % stator earth fault protection based on subharmonic injection, a 20Hz voltage is injected into the generator star point. The 20-Hz generator SGEN-1001 is used in combination with the Band Pass Filter SBPF-1001 in the Stator Earth fault protection. The injection can be performed by connecting the SGEN-1001 and the SBPF-1001 to the load resistor of an earthing or neutral transformer. If an earth fault occurs in the generator star point, the 20 Hz voltage drives a current through the fault resistance. From the driving voltage and the fault current, the protective relay determines the fault resistance.
