Product Description

1–3

In addition to the synchronization function, the LSM provides an extensive
array of monitoring information for systems wired in Wye, Delta, or Open
Delta. The monitored data is shown below:

Table 1.1

Current in Amps (per phase & neutral)

Average Current in Amps

Positive Sequence Current in Amps

Negative Sequence Current in Amps

Percent Current Unbalance

Voltage in Volts (per phase L–L, also L–N on 4–wire systems)

Average Voltage in Volts (L–L, also L–N on 4–wire systems)

Positive Sequence Voltage in Volts

Negative Sequence Voltage in Volts

Percent Voltage Unbalance

Synchronizing Bus

Frequency in Hz

Synchronizing Bus

Phase Rotation (ABC, ACB)

Power Factor in Percent (total, also per phase on 4–wire systems)

Watts (total & per phase on 4–wire systems)

VA (total & per phase on 4–wire systems)

VAR (total & per phase on 4–wire systems)

Power Consumption in kW Hours

Reactive Power Consumption in kVAR Hours

Demand (Amps, VA, & Watts)

Voltage per phase in Volts (per phase L–L, also L–N on 4–wire systems)

Average Voltage in Volts (L–L, also L–N on 4–wire systems)

Reference Bus

Frequency in Hz

Phase Rotation (ABC, ACB)

All voltage and current measurements are true RMS. The power
measurements are calculated from the instantaneous voltage and current
measurements. The remainder of the monitoring information is derived from
these values.

Before the LSM can perform its intended functions, it must be configured by
the user. The module is configured by providing the required data via a block
transfer to the module. The block transfer data can be entered into the PLC-5
manually or with the 6200 Version 4.4 I/O Configuration Software. The 6200
Software can also be used to monitor the operation of the module.
