Description
Application example
Batteries in power plants and transformer substations must provide
the equipment they serve with standby power in the event of a
power failure. Unfortunately, however, the capacity of such batteries can drop significantly for a number of reasons before their
calculated life expectancy is reached. This is why it is so important
to check batteries at regular intervals, and the only reliable way of
measuring battery capacity is to conduct a discharge test.
Testing can be carried out without disconnecting the battery from
the equipment it serves. Via a DC clamp-on ammeter, TORKEL measures total battery current while regulating it at a constant level.
TORKEL™ 840 - UTILITY is used for battery systems ranging from 12
to 250 V – often encountered in switchgear and similar equipment.
Discharging can take place at up to 110 A, and if higher current is
needed, two or more TORKEL 840 units or extra load units, TXL,
can be linked together. Tests can be conducted at constant current,
constant power, constant resistance or in accordance with a preselected load profile.
TORKEL 860 - MULTI is designed primarily for people who travel
from place to place to maintain battery systems having different
voltages. It features excellent discharging capacity plus a broad voltage range and outstanding portability – a unique combination.
TORKEL 860 is used for systems ranging from 12 to 480 V, and
discharging can proceed at up to 110 A. If higher current is desired,
two or more TORKEL 860 units or extra load units, TXL, can be
linked together. Discharging can take place at constant current,
constant power, constant resistance or in accordance with a preselected load profile.
The TORKEL is connected to battery, the current and the voltage
alarm level are set. After starting the discharge TORKEL keeps the
current constant at the preset level. When the voltage drops to a
level slightly above the final voltage, TORKEL issues an alarm. If the
voltage drops so low that there is a risk for deep discharging the
battery, TORKEL shuts down the test. The total voltage curve and
the readings taken at the end of the test are stored in TORKEL Later,
using the TORKEL Win program (optional), you can transfer these
readings to your computer for storage, printout or export. If your
PC is connected to TORKEL during the test, TORKEL Win builds up
a voltage curve on the screen in real time and displays the current,
voltage and capacity readings. You can also control the test using
TORKEL Win.

TORKEL and TXL can be combined into systems to match up for different battery capacities. These resistive extra loads do not perform
any regulating functions. They are designed for use together with
TORKEL Battery Load Units. Their purpose is to provide higher
load currents for use in constant current or constant power tests.
Together, TORKEL and the TXL Extra Loads form a system that can
discharge batteries with currents of up to several kA. TXL Extra
Loads are connected directly to the battery, and TORKEL measures
the total current using a clamp-on ammeter.
TXL Extra Loads are shut down automatically when TORKEL is
stopped.
