1.3 Amplifier for Voltage and Current

Current generator and voltage generator have no current booster and no voltage booster, but direct
coupling mode is adopted by them, which enables the power supply’s frequency output range to be
from 0Hz to 1000Hz, outputting DC and all AC voltage or AC current in all frequency. Such as
square waveform, varying waveform in proportion with the exponential function as well as mixed
Reclosing waveform. Basically it meets the transient testing requirements of the protection device,
thereby achieving the simple simulating test on various protection devices.
Power amplifier circuit has the perfect protective function against over-current, over-voltage and
over-temperature so that keep the high-power components of the set from damage in the test. When
the power amplifier is charged, the internal circuits of protection relay will real-time monitor/detect
the output current value from the voltage circuit and determine whether the detected current values
are overload. When there is overload or short-circuit in the circuit voltage, the power of the power
amplifier will shut down automatically and the test will stop, giving out the warning signal.

1.6 Attention:

z There are good Grounding picture in the right bottom of each interface menu.

The grounding link is abnormal if showing picture
In order to insure the test security and the accuracy of testing result, please check the power

supply whether the grounding is proper.

z It is prohibited to connect the host instrument with 380V three-phase AC or DC power supply.
z Before testing, the grounding line jack must be reliably grounding; otherwise it might damage

the Relay Tester.

z The voltage circuit can not be short circuit or overload, and the load of the current circuit

should meet Impedance values under the given technical parameters so that avoid the overload
affecting the testing results.

z In case that there is overload or short-circuit in the voltage generator, the Relay Tester will

automatically shut down the power of the amplifier power and give out warning signal.
Maximum current load in each phase is up to 0.55A for the voltage generator.

z In case that the large current has been output for a long time, and as a result, the power

amplifier’s temperature is at high degrees, the Relay Tester will automatically shut down the
power of the amplifier power and give out warning signal, User shall stop test right until the
amplifier power gets cool.

z Binary Input’s potential is directional. So better to use idle contact as usual.
z Negative terminals A, B, C of Binary input are all connected together, but not connected with

the public terminal ‘N’ of voltage / current output terminal and the ground wire (such as panel,
machine box) that is the suspending ground. Binary Input’s terminal is compatible with the idle
contact and the potential (10-250V). However, Binary Input’s terminal has directionality for the
input of the charged contact, as shown in the Figure below, A, B, C and R are connected with
the high potential (+),the negative terminal are connected with the lower potential (-) of the
charged contact, and then the computer can detect the overturn of the contact state. If the
connections are in reverse, what will always be detected will be the closed state.

z If there is emergency in the process of the test, the Power Amplifier button must exit rapidly

and then to shut down the power of the host of Relay Tester.

3.3.2 Parameter setup of the set:

Variable : including Amplitude Value, phase and frequency, one of which can be chosen as a

variable and eight channels（five-way voltage and three-way current）of which can also

be chosen as variable output.
Test mode: including Automatic test and manual testing mode.
Auto: Control Action value, Return Value and Return Coefficient of the testing variables through

setting variable mode, automatic test time and variable step size. When testing, the
variable will increase or decrease by degrees from the starting value to the final value in
accordance with automatic time and step size; when doing an excessive test, set step
size to the positive and the starting value set must be less than the final value; when
doing an inadequate test, set step size to the negative and the starting value set must be

more than the final value. Note: Click ‘Stop’ button to stop the test and then amend the
parameters to retest if a new test is required by changing the parameters in the

automatic test.

Manual : Control the test manually by variable step size of ‘＋’ Manual increase or‘-’ Manual

decrease. When testing, the change of the variable will not be controlled by the change
time and not be limited by the final value, step size will not be set to the negative, and
the test of increase or decrease by degrees can be done by +Manual increase and

-Manual decrease; when Binary Input receives the action signal and then the test stops,

16

K68 Series Protection Relay Test Set

[e-mail]

meanwhile, action time and action value are recorded. After testing, the setup
parameters will be changed to re-test without clicking ‘Stop’ button to stop the test, for

the parameter can be changed directly.
Mode : Only adapt to Automatic test, including ‘Action stops’ and ‘Action returns’ mode.
Pick-up: Variables change to strop from the starting value to the final value in accordance with step

size or receive the protection signal to stop the testing process in the process of the

change. Action time and Action value will be automatically recorded and action value

or Return Value of the variable can be tested.
Drop-off : Voltage or current variables change from the starting value to the final value in

accordance with step size, when the protection action signal is received, the variable

will begin to return to the starting value until return signal is received, when Action

stops, action time, action value, return value and return coefficient will be recorded.

Action value, return value and return coefficient will be automatically tested.
Steps(s): when automatically testing, the time of step size changes once for the variable, the

automatic time generally set should be more than Action time and Return Time of the

relay, Maximum Automatic testing time is set to 1000s. When manually testing, users

can grasp the changing time.
Deglitch(s): JitterBuffer time, Deglitch(s) generally can be set to 15ms, it functions when the tested

result is affected due to the jitter of the protection access point in the process of testing

during automatic test, only after the lasting period when the access point is closed or

disconnected meets the set time, the located state is authorized.
