Full Description of these Prepaid Meters
The Cashpower Three Phase PLC meter is a four-
The meter boasts a large custom display and also features a host of standard Cashpower software features including the ability to operate as a prepayment meter or in credit metering mode.
Split Metering Functionality
The split prepayment meter consists of two parts, the meter and the customer interface unit. Communication between the meter and the customer interface unit is by means of Power Line Communication (PLC), using existing household wiring. No additional communication wires are required.
The customer interface unit is compact with a user-
The meter is usually installed in a secure, locked enclosure, typically a pavement kiosk. It is outside the consumer’s home to facilitate easy inspection by the utility at any time and to reduce the opportunity of fraud by tampering.
A key feature of the Cashpower Three Phase PLC split prepayment meter is the ability to use standard household wiring for communication between the customer interface unit and the prepayment meter. This capability enhances retrofitting or replacement of conventional meters with prepayment meters.
The benefits include lower cost of installation as no new cabling needs to be laid, and speed of installation.
The keypad or customer interface unit is simply plugged into any existing mains outlet and after a simple commissioning procedure, the unit communicates with the remote meter up to a distance of typically 200 metres.
The maximum communication distance is dependent upon network attenuation and interference.
The customer interface is connected by a power cord to an existing mains outlet in the household. Under normal conditions, when there is sufficient credit in the meter, the customer interface unit operates directly from mains voltage. However in the event that the meter credit expires and the meter disconnects power to the house, the customer interface unit is fitted with two standard AA Alkaline batteries to allow the customer to re-
The customer interface has a large backlit display with configurable functionality. The customer or field technician can access meter parameters by entering specific register information using the keypad.
In addition, the customer interface unit has audible low credit warning tones that can be silenced with a key press.
Meter status and diagnostic indicator
The meter includes a LED status indicator. This allows a technician to view the operational status of the meter without the need for specialised interrogation tools or having to gain access to the consumer’s premises. Information such as tamper status, power limiting, commissioned status and credit status are available.
LCD display on the meter
The standard Three Phase PLC prepayment meter is available with a large clear display to enable field staff to read the meter parameters in a secure kiosk. This meter can be configured at the time of manufacture to show total kilowatt-
As a standard feature, the Three Phase PLC meter offers an IEC 62056-
The split configuration of Three Phase PLC meters significantly reduces the risk of tampering, especially considering that the meter is installed in a remote, secure location. The meter is also mechanically sealed against tampering through the use of factory-
In addition, the meter is equipped with a tamper sensor that will automatically disconnect the power to the load in the event of tampering.
The meter also has a feature allowing detection of Significant Reverse Energy. If the line and load wires are swapped during installation, the meter will continue to operate and decrement credit but can be factory programmed to tamper and disconnect the load should Significant Reverse Energy be detected.
The meter is capable of “upstream” communication to a concentrator at a kiosk, low-
This feature enables the Three Phase PLC meter to be remotely accessed by the utility to check the remaining kilowatt-
Communications capability can be implemented in two ways. A concentrator, supplied by Landis+Gyr or a third party, can be fitted into the secure enclosure to provide connectivity via wireless technology to a power utility’s back office. As with all Cashpower split prepayment meters, the Three Phase PLC has an optical communications port and each meter in the enclosure is connected to the concentrator via an optical port reading device.
By means of the concentrator and the optical communication port, bi-
Prepayment / Credit feature
These include the anti-
The meter can be switched between credit mode and prepayment mode when necessary, using a 20-
The meter has been designed to have a surge voltage withstand that significantly exceeds the requirements of both SABS 1524 and IEC 62052-
