The Short-time Overcurrent Test Equipment (STOC) is critical for ensuring that energy meters comply with standards such as IEC 62053 and IS 13779. This equipment helps verify that energy meters can withstand short bursts of overcurrent without damage, maintaining accuracy once normal conditions are restored.

Here’s a summary of its key features and uses:

1. Purpose and Standards Compliance:

   • Objective: To measure and analyze how short-time overcurrents affect energy meters.
   • Standards: Adheres to IEC 62053, IS 13779, and similar standards that mandate meters must withstand overcurrents without permanent damage and with minimal error variation.

2. Functionality:

   • Impact Testing: Ensures that energy meters do not suffer damage from short-term overcurrents and operate correctly afterward.
   • Error Margin: Measures that the deviation in meter accuracy is within permissible limits specified by the meter’s class.

3. Equipment Overview:

   • Models: STOC 01, STOC 02, and STOC 03.
   • Components:
     • Power Circuit: Delivers the overcurrent to the Unit Under Test (UUT).
     • Control Panel: Provides a user interface to set parameters and manage test conditions according to standards and specific UUT requirements.

4. Applications:

   • Testing Laboratories: For routine compliance and performance checks.
   • Research and Development Centers: To develop and validate new meter technologies.
   • Manufacturers: For quality assurance and type testing before meter distribution.
   • Energy Distribution Companies: Ensures meters meet regulatory requirements for listing and use.

Overall, the STOC series is designed for rigorous testing, ensuring energy meters can handle short-term overcurrents reliably while maintaining performance and accuracy.

Short-time Overcurrent Test Equipment is utilized to measure and analyze the effects of short-time overcurrents on energy meters. This test is outlined in various standards for energy meters, such as IEC 62053 and IS 13779.According to CEI/IEC 62053, short-time overcurrents should not damage the meter. The meter must operate correctly when returned to its initial working condition, and the variation in error should not exceed specific values based on the class of the energy meter.The Short-time Overcurrent Test Equipment is suitable for testing the impact of short-time overcurrents on all types of energy meters that must conform to or exceed the requirements of national and international standards. STOC 01/02/03 is ideal for use by testing laboratories, research and development centers, and manufacturers for conformity assessment services, research, and type testing. This test is mandatory for electronic and electromechanical energy meters supplied to energy distribution companies that require listing by reputable assessment agencies.The STOC 01/02 consists of a power circuit and a control panel. The power circuit delivers the ‘overcurrent’ to the Unit Under Test (UUT). The control panel provides the user interface to adjust the parameters as per the requirements of the standards and the UUT.
