Conventional Energy

Generator sets must offer reliability, low

maintenance and long life wherever

they are installed: construction sites,

infrastructures, industries, agriculture.

In generator sets it is necessary to

measure, display and control all the

main variables relevant to the power

produced, including harmonic distortion.

The “Advanced” version of the 3-phase

power analyzer WM14 and of the

correspondent transducer model

CPT-DIN, are the optimum for this

application. The PLC-type alarm control

on 16 variables allows the anomalies

to be divided into two groups:

critical problems (phase loss, under-

voltage, frequency, with OR logic) can

automatically lead to the disconnection

of the generator set, with a horn or lamp

warning; non-priority anomalies can

be transmitted to the supervisor system

via the serial port. The WM14 and CPT

Advanced give the possibility of counting

the generation hours and to monitor

different parameters (from the current

to harmonic distortion), also storing

the peak and valley values. The most

critical gen-set applications need an

even more sophisticated control system:

the modular power quality analysers

carry out this task perfectly, also with

data-logging capabilities in the case

of the WM40. The simpler generators

can be monitored by temperature,

frequency, and/or voltage relays while

co-generation systems feeding the

public grid need an interface protection,

capable of disconnecting the generator

from the grid in case of mismatching

of the main electrical parameters. The

interface protection relay is approved

according to National standards when

required, as per our monitoring relay

types DPC02 and DPC72.
