Description

GENY's meter test systems adopt the most advanced electronic measurement technology and modular concept combine the differential reference standards and power amplifiers to meet the requirements of customers in electric energy meter manufacturers, electric power utilities, metrology laboratory, measurement and quality inspection departments and factories or enterprises.

The YC1893D Meter Test System is a fully automatic system for testing and calibrating single phase and three phase electrical energy meters, consisting of the following components

• Three-phase Power source
• Three-phase Reference standard meter
• Meter suspension test racks for testing of both 1-phase/3-phase meters
• Smart meter function test system (fixed voltages, optical probe, relay control test and ripple control box as option)
• Other necessary parts
• PC and software controlling the whole system

The YC1893D meter test system is fully compliant with the IEC 60736 standard and is suitable for testing meters according to the following standards:

• IEC 62052-11 and IEC 62053-11, -21, -22, -23, -24
• IEC 62056
• EN 50470-1, EN 50470-2, EN-50470-3
• IEC 61010

Safety

Users of testing equipment from GENY have the ultimate responsibility to ensure that anyone working on or near the equipment follows all relevant safety precautions. Safety measures must comply with the requirements specific to this type of testing equipment. In addition to the standard regulations that apply to the workplace, follow the below recommendations. Trained personnel with extensive testing equipment operation knowledge must conduct all work. To prevent injury or fire hazards, do not power on the machine if it is damaged or suspected to be faulty. Avoid operating the machine in damp, wet, condensing, dusty, or explosive gas environments. Incorrect equipment operation can result in hazardous situations, causing harm to the operator and damage to the machine.
