以下各节及其子节包含以下信息：

调试检查所需的设备和设施。

调试检查所需的程序；例如，取决于要测试的组件：保护、联锁条件、通信、测量值记录和确定方向。
5.1安全信息

5.3测试设备
REF542plus调试的重要设备是适当的继电器测试设备。测试设备应具有三相电流，并且
电压系统。此外，还应能够通过测试设备模拟电流和电压传感器。例如，KOCOS制造的测试设备
在科巴赫/德国可以使用。
5.4测试联锁条件，
该测试旨在检查用户想要的开关设备的联锁
并且是必需的。这里必须考虑两种类型的联锁：
特定开关设备的间隔级联锁，以及
间隔与其他间隔的车站级联锁。
被测隔间的联锁条件可在订单文件中找到。用户指定的联锁条件可在此处找到。
必须检查所有可能的情况。

5.5确定变压器方向
测量输入的连接和电流的正确极性，以及
电压互感器或传感器对于距离、比较和方向功能非常重要。
除测试极性、变比和磁化特性外，还必须检查变压器/传感器的接线
测验
5.5.1电流互感器
变压器必须有正绕组。
这可以用9V电池和模拟直流电压表轻松检查。如果电流互感器的初级线圈连接到蓄电池，则模拟电压表
二次侧的连接必须为正极。断开蓄电池时，电压表必须测量负脉冲。
蓄电池正子必须连接到初级线圈的P1，并且
本测试中电压表的正极输入至s1。这同样适用于负片
初级线圈P2处的端子和次级线圈s2处的电压表负输入。

 Commissioning
The following sections with their subsections contain information on:

The devices and facilities required for the commissioning inspection.

The required procedure for the commissioning inspection; For example, depending on the components to be tested: Protection, interlock conditions, communications, measured value recording and determining the direction.
5.1 Safety Information
The devices, adapters and procedures described are only examples. Experience and
safety in handling the various devices is a requirement.
5.2 Switching on the feeder

Caution Before switching on the feeder check that the REF542plus is fully functional in
the corresponding bay. Pay particular attention to the protective functions and
the interlocking!
5.3 Test Equipment
The most important device for the commissioning of the REF542plus is an appropriate relay test equipment. The test equipment should have a three phase current and
voltage system. Also the simulation of current and voltage sensors by the test equipment shall also be possible. For example a test equipment manufactured by KOCOS
in Korbach/Germany can be used.
5.4 Testing the interlock conditions,
This test is intended to check the interlocking of the switchgear that the user wants
and is required. The two types of interlocking must be taken into account here:
Bay-level interlocking of specific switchgear and
Station-level interlocking of the bay versus other bays.
The interlock conditions for the bay under test can be found in the order documentation. The interlock conditions specified by the user can be found there.
All possible circumstances must be checked.

5.5 Determining the transformer direction
The connection of the measuring inputs and the correct polarity of the current and
voltage transformers or sensors is very important for distance, comparison and directional functions.
In addition to testing the polarity, the transformation ratio and the magnetizing characteristic, the wiring of the transformers/sensors must also be checked during these
test.
5.5.1 Current transformer
The transformers must have a positive winding.
This can be easily checked with a 9 V battery and an analog DC voltmeter. If the primary coil of the current transformer is connected to the battery, the analog voltmeter
connected on the secondary side must show positive. When the battery is disconnected, the voltmeter must measure a negative impulse.
The positive terminal of the battery must be connected to P1 of the primary coil and
the positive input of the voltmeter to s1 for this test. The same applies for the negative
terminal at P2 of the primary coil and the voltmeter negative input at s2 of the secondary coil.
The test setup for checking the direction of a core is shown in the following figure.

Figure 16: Setup for the polarity test of current transformers
This polarity check, also referred to as patch test, must be run for every core. To
guarantee correct operation even with a multi core current transformer with different
cores such as protection and measuring cores, it is recommended that the magnetizing characteristic (hysteresis) be recorded. A Variac with appropriately high voltage is
connected to the secondary terminals. The flowing current is measured while the output voltage is rising. The characteristic of the measured values, voltage over current,
yields the magnetizing characteristic of the core, which can then be compared with
the manufacturer's data.
The transformation ratio of the current transformer cores is checked with a special
primary current feed device. The feed device is primarily connected to the current
transformer and the secondaray value is measured at the secondary terminals of the
transformer or at the protective cabinet with an ampere meter
