Foreword
This Standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard is developed and mainly referenced to GB 9254 “Limits and methods of
measurement of radio interference characteristics of information technology
equipment”, GB/T 17618 “Information technology equipment - Immunity characteristics
- Limits and methods of measurement”, GB 19286 “Electromagnetic compatibility
requirement and measurement methods for telecommunication network equipment”.
This Standard replaces YD/T 983-1998 “Limits and methods of measurement of
electromagnetic compatibility for telecommunication Power supply equipment” from
the date of implementation.
Compare with YD/T 983-1998, the main changes of this Standard are as follows.
- SPECIFY that the telecommunication power supply equipment in this Standard
does not include UPS (see Clause 1);
- ADD the frequency range of 1 GHz ~ 6 GHz for radiation disturbance test (see
8.2).
- MODIFY the classification and limits of harmonic current equipment (see 8.3);
- EXPAND the frequency range of radiated, radio-frequency, electromagnetic field
immunity to 2.7 GHz (see Clause 9);
- SPECIFY the immunity level of telecommunication power supply equipment in
telecommunication centers and other-than-telecommunication centers (see
Clause 9).
Attention is drawn to the possibility that some of the contents of this document may be
the subject of patent rights. The issuing agency of this document shall not be held
responsible for identifying any or all of such patent rights.
This Standard was proposed by and shall be under the jurisdiction of China
Communications Standards Association.
This Standard is drafted by Telecommunication Research Institute of the Ministry of
Industry and Information Technology of the People’s Republic of China.
Main drafters of this Standard. Tang Weisheng, Zhou Yi, Zhang Yunzhuan, Lu
Bingsong.
This Standard was first issued on October 28, 1998. This is the first revision.
Limits and methods of measurement of
electromagnetic compatibility of
telecommunication power supply equipment
1 Scope
This Standard specifies the electromagnetic compatibility requirements for
telecommunication power supply equipment (hereinafter referred to as TPE, excluding
UPS, generator and battery), including limits, performance criteria and measurement
methods, etc.
This Standard applies to the power supply equipment for telecommunication switching
equipment, telecommunication transmission equipment and wireless communication
equipment.

4 Test conditions
4.1 General conditions
The TPE shall be tested under normal test conditions. The test conditions shall be
recorded in the report.
Regardless whether the TPE requires special software or test fixtures to connect to
the host equipment, the test layout shall be as close to the normal or typical actual
operation state as possible.
The test conditions of the TPE shall be as close to the actual installation conditions as
possible, and the wiring shall be consistent with the actual process. If the TPE is to be
installed in a rack or an enclosure as specified by the manufacturer, unless otherwise
stated, the TPE shall be installed according to the method stated in the instructions or
the installation manual.
If the equipment is part of the system or is connected to the ancillary equipment, the
equipment shall be connected to the ancillary equipment of the minimum typical
configuration during the test, however, the port connected to the ancillary equipment
shall be activated.
If the equipment has a large number of ports, it shall select a sufficient number of ports
to ensure that the actual situation can be simulated and that different types of ports
can be tested.
If the TPE consists of multiple telecommunication power supply modules, each
telecommunication power supply module shall be tested.
Measures shall be taken to avoid the effects of immunity test signals on the measuring
equipment and test ancillary equipment (e.g. signal sources, ancillary equipment, etc.)
located inside/outside the test environment. Measures shall be taken to avoid the
effects of auxiliary test equipment located inside/outside the test environment on the
test result.
During the test, the mode of operation and configuration shall be accurately recorded
in the test report.
Unless otherwise specified in the product instructions, the TPE shall be connected to
the resistive load.
The signal or control port shall be properly connected with the necessary AE or nominal
resistance.
