Tyco 1540 - Manual (Page 9)

1.1.4 1000
The 1000 will display the following parameters:
• System voltage (average of all phases)
• System current (average of all phases)
• System frequency (Hz)
• Voltage line to neutral for each phase (4-wire systems only)
• Voltage line to line for each phase (calculated in 4-wire)
• Current in each line
• Neutral current 1
• Power Factor
• Active Power (kW)
• Reactive Power (kVAr)
• Apparent Power (kVA)
• Active Energy (kWh) 2
• Reactive Energy (kVArh) 2
• Total System Current Demand (AD) 2
• Total System Active Power Demand (kWD) 2
• Maximum Total System Current Demand (AD) 2
• Maximum Total System Active Power Demand (kWD) 2
The 1000 has Set-up screens for:
• Full-scale current value
• Potential transformer - primary voltages.
• Demand integration time and energy/demand resets
• Pulse output duration and rate divisor (option)
• RS485 serial Modbus parameters (option)
A pulsed relay output, indicating kWh, and an RS485 Modbus TM
output are available as optional extras. The Modbus output
option allows remote monitoring from a Modbus master.

Neutral referenced parameters are only available when used with 4-wire and single phase
configured transducers.
2
All energy and demand measurements are importing only unless connected as exporting unit.
