EMC Partner systems for EFT, Surge and DOW can all be coupled through one single device: The CDN3000A-06-32 2 Electricity Meter Test System Testing of electricity meters has evolved to take account of the increasing use of electronics. Apart from tests of electrical safety, Electricity meters must be tested for Electromagnetic Compatibility (EMC) relevant to the installation en- vironment and in more modern electricitry meters, tests against disturbance caused by mains signalling must be conducted. EMC PARTNER special- ize in test equipment to simulate the impulse and short duration disturbances that can be propogated down the power mains. By their very nature, most elec- tricity meters are required to operate in three phase power main systems. Impulse Voltage Tests Impulse transients can be generated by external events such as lightning or internal events like switching. The result is a voltage impulse with low energy content that ap- pears between windings in transformers, between power lines or across physical gaps between conductors and cases etc. A normalised voltage impulse of 1.2/50us is defined in the standards IEC 60060-1 and IEC61180-1. Fast Transient (Burst) Tests Industrial measurement and control equipment nearly always use conventional control units containing relays or other electro-mechanical switching devices. Fluorescent lamp ballast units, insufficiently suppressed motors (hair dryers, vacuum cleaners, drills, etc.) are found everywhere in the public power supply. EFT is defined in the basic standard IEC 61000-4-4 Combination Wave Tests (CWG) Surge events are generated by lightning phenomena, switching transients or protec- tion devices in the power distribution system. A surge is influenced by the propogation path resulting in different forms depending upon where a measurement is taken. Combination Wave Generators (CWG) simulate a surge event in power lines close to or within buildings. Surge is defined according to IC 61000-4-5 Dips & Interrupt Tests Voltage failures occur following switching operations, short-circuits, response of fuses and when running up heavy loads. The interference sources in the mains, caused by electronic power control with non-linear components e.g. thyristors are used more frequently in domestic appliances. IEC 61000-4-11 defines DIPS & Interrupts. Damped Oscillatory Waves (DOW) Damped oscillatory waves occur mainly in power, control and signal cables installed in air insulated (AIS) high voltage and medium voltage (HV/MV) substations. The event has a relatively high transfer impedance resulting in a voltage impulse. A normalised voltage impulse of a damped sinewave as defined in the standards IEC 61000-4-18 and ANSI C37.90 are an industry standard. Electrostatic Discharge Tests The capacity of the body can be charged to several kilovolts and is discharged when contact is made with an electronic unit or system. The discharges are harmless to humans, but not to sensitive, electronic equipment. The resulting currents cause interference or even component damage. ESD is defined in IEC 61000-4-2. Differential Mode Testing Designed according IEC61000-4-19 to generate and inject differential mode distur- bances in the frequency range 2 kHz – 150 kHz, the system allows testing smart electricity meters or different devices connected to the AC power network, where disturbances from mains signalling, inverters or other power electronics is present.

With EMC PARTNER impulse test equipment, the insulation test, Eelctrical tests and Electromagnetic Compatibility tests (EMC) are reduced to managable levels. Your aim is to test and approve electric- ity meters as fast as possible. EMC PARTNER can help. Smart Meter The addition of electronics and control interfaces to energy meters has created the need for more tests to ensure reliable energy measurement and reporting. In particular when mains signalling is used, there is a need to perform differential mode tests on the power interfaces. IMU SMART SLAVE V1I1 accomplishes this task in a single unit including the CDN to decouple interference signals from a reference meter and also a 25A current source to allow Ib setup without external equipment.
