AE -1440 is developed specific for Utility Substation applications. .AE 1440 computes -Display, Monitor, stores, and communicate up to 67 major electrical parameters, including true RMS Voltage, Current, PF, Frequency, Active power, Reactive power, Apparent power, Active energy, Reactive energy, Apparent energy, Total harmonic distortion (THD) and Maximum demand. The meter offers simple user-friendly Programming of Voltage, current, and power Measurement parameters using a menu driven interface. Status of all parameters can be viewed through 30 main Screens on the 3 line, 4 digits LED display. The AE -1440 has digital RS485 Communication outputs for MODBUS and is ideal for Energy Management System at Electrical Substation.

Operation

AE 1440 offers high functionality and uncomplicated operation. AE- 1440 measures all the values needed to monitor power and Energy. A five-button interface on the front panel gives simple access to the measuring, display and configuration screens. With the help of A (navigation key) buttons, we can access total 67 major electrical parameters. The parameters to be viewed through display screens.

AE Dual Source KWH meter measures energy (Watt hour) Of both MAINS as well as GENSET, consumed in, Three phase 2 / 3 element, 3 / 4 Wire, balanced / unbalanced load circuits. The meter comprises of advanced microcontroller technology for reliability & accuracy. The user-friendly operation is the unique feature of this meter.

It is used to measure the applied frequency, functionally similar to vibrating reed meter. The meter incorporates light emitting diodes LEDs which are used instead of vibrating reeds to indicate applied frequency. The frequency is determined by blinking LEDs. When applied frequency matches with the frequency marked on the dial, that particular LED blinks with maximum intensity. When the applied frequency is mid way between two adjacent LEDs, both LEDs blink. When the meter is switched on all the LEDs glow sequentially for a period of 1 to 1.5 seconds, thereafter it will indicate the applied frequency.

All voltage ranges are available in single meter. Terminal screws with washers are provided only for specific voltage as per requirement & remaining two terminals are covered with insulated caps.In case of 96mm & 144mm instruments, two sets of LEDs with the same scale range can be offered, giving two independent meters in one casing (Dual Scale). This facilitates in comparing the frequency of two voltage supplies for paralleling operation.

Features :

• No vibrating parts.
• No aging effect.
• Faster response.
• Lighter in weight.
• Low power consumption
• No effect of external vibration
• Visible in dark & from distance.

It is used to measure the applied frequency. Vibrating Reed Frequency meters indicate the supply frequency by means of individual reeds, when rated voltage 20% is applied across the terminals of the meter, the particular reed, whose natural frequency of vibration coincides with the supply frequency, vibrates with full amplitude. In case the supply frequency falls midway between two reeds both the reeds vibrate, at reduced amplitude. The amplitude of vibration at the tip of reeds is high enough for a distinct indication.

The instrument can be operated at 110V, 220V, or 440V. Terminal screws with washers are provided for the selected operating voltage & remaining two terminals are covered with insulated caps.In case of RFD96 and RFD144 instruments, two sets of reeds with the same scale range can be offered, giving two independent meters in one casing. This facilitates in comparing the frequency of two voltage supplies for paralleling operation
