Transformer Anti-theft Protection System ZAT
PURPOSE
Transformer Anti-theft Protection System – ZAT system – it is a system used for protection against the theft of devices installed over a large area and connected to the low voltage power network.
The task of the system is a quick and reliable trasmission of information on interference in the device to its owner.
ZAT-1 sensor it is a device for continuous monitoring of the object protected. The device is resistant to ambient conditions typical for the Polish climate.
SPECIFICATION
The following elements are used as sensors of interference in the protected device:
- three-phase voltage sensor,
- vibration sensor (position sensor),
- contact sensors,
- sensors of opening the casing.
On account of the operating speed and costs of data transfer the basic method of communication in the system is GPRS transmission. ZAT-1 sensors can also send SMS messages. In case of problems with GPRS, the system may use SMS messages for the
transfer of information.
The system consists of:
- ZAT-1 sensors,
- GSM system provided by cellular network operator,
- The system server installed at the system owner head office,
- GSM modem – optional.
ZAT system may operate using the APN number of the mobile network operator. However, in order to protect the system against the attacks of hackers it is strongly recommended to the user to buy the private APN service from mobile network operator, that allows complete separation of ZAT system from the public internet network.
TECHNICAL SPECIFICATION
| The possibility of data transmission by means of GSM communication |
The sensor uses two methods of data transfer: |
| One input of three phase voltage | The voltage is monitored continuously. The input generates events of loss and switch on of the voltage. |
| Three two-state inputs – contact type | For every input the following states may be defined: - Input signal description - Short name of the input signal - The type of reaction to closing and opening of the input - The change of an input signal response time (short changes filtering) |
| Vibration sensor | Three axis acceleration sensor. |
| Sensor of opening the casing | + |
| Temperature sensor | + |
| Set of LEDs allowing to determine the device functional state | + |
| Diagnostic communication allowing to trace the GPRS operation in case of problems with logging to GSM system | + |
| USB interface allowing to configure and supply of ZAT-1 system (including charging of battery) | + |
| Power supply |
Battery fitted allowing for min. 8 hours operation of ZAT-1 without external supply. |
| Dimensions |
80 x 55 x 160 mm |
| Weight [without external conductors] | 0,35 kg |
