Measuring Values

Measuring principle

The device measures alternating voltage utilizing a sampling measuring method. All

values are sampled for each phase with a rate of 5 kHz, integrated over one period, and

the RMS value is calculated. The frequency is established from the time intervals of the

voltage passing through zero.

Measuring values

Direct configuration cable (DPC)

The DPC cable is used to configure the device with the ToolKit configuration software and

external extensions/applications.

There are two versions available:

•DPC-USB direct configuration cable •

•DPC-RS-232 direct configuration cable •

DPC-USB direct configuration cable

Use the DPC-USB direct configuration cable if you want to connect the Woodward

controller to an external device (master) which is equipped with an USB port.

Order item number:

•DPC-USB direct configuration cable – P/N 5417-1251

DPC-RS-232 direct configuration cable

Use the DPC-RS-232 direct configuration cable if you want to connect the Woodward

controller to an external device (master) which is equipped with an RS-232 port.

Order item number:

•DPC-RS-232 direct configuration cable – P/N 5417-557

Configuration

All parameters are assigned a unique parameter identification number.

The parameter identification number may be used to reference individual parameters

listed in this manual.

Homepage

General notes

The ToolKit “Homepage” gives an overview of all measured values, the state of the relays

and the state of the monitoring.

The “Homepage” is only used to display values. The values cannot be adjusted here. The

configuration of the parameters is done in the other menu sections on the left hand side.

The following chapters describe all menus in detail.

Configuration

4.2.1 Measurement

General notes

The setpoints for specific parameters will differ depending upon the hardware version,

indicated on the data plate

The AC power triangle illustrates the dependencies between active power, apparent

power, reactive power and power factor.

•PF = P/S = cos Φ •

•Q = √(S2-P2) •

•S = √(P2+Q2) •

•P = S * PF

Monitoring

4.3.1 Overvoltage (Level 1 & 2) ANSI# 59

General notes

Voltage is monitored according to how the parameter “Voltage measuring”

(parameter 1851) is configured. This controller provides the user with two alarm levels for

overvoltage. Both alarms are definite time alarms.

Monitoring for overvoltage faults is performed in two steps.

The diagram listed below shows a frequency trend and the associated pickup times and

length of the alarms.

Undervoltage (Level 1 & 2) ANSI# 27

General notes

Voltage is monitored according to how the parameter “Voltage measuring”

(parameter 1851) is configured. This controller provides the user with two alarm levels for

undervoltage. Both alarms are definite time alarms.

Monitoring for undervoltage faults is performed in two steps.

Overfrequency (Level 1 & 2) ANSI# 81O

General notes

This controller provides the user with two alarm levels for overfrequency. Both alarms are

definite time alarms.

Monitoring for overfrequency faults is performed in two steps.

The diagram listed below shows a frequency trend and the associated pickup times and

length of the alarms.

Underfrequency (Level 1 & 2) ANSI# 81U

General notes

This controller provides the user with two alarm levels for underfrequency. Both alarms

are definite time alarms.

Monitoring for underfrequency faults is performed in two steps.

The diagram listed below shows a frequency trend and the associated pickup times and

length of the alarms
