The SC 23-1 model is a robust, weatherproof unit built for long-term outdoor operation without requiring an external power source
- Functionality:
- Surge Counting: It uses a reliable mechanical counter (typically 6 digits) to record each significant discharge event through the arrester.
- Leakage Current Monitoring (Optional Variant): Many EHV counters/monitors, including typical CG models like the SC 07-1, incorporate an analog milli-ammeter to measure the total continuous leakage current. This aids in online condition monitoring, as significant changes in leakage current can indicate arrester deterioration or contamination.
- Construction and Durability:
- Housing: Housed in a durable, powder-coated aluminum or stainless steel casting for resistance to corrosion and environmental factors.
- Weatherproof: Tested for ingress protection of at least IP55 (some specifications mention IP67 for certain variants), ensuring protection against dust and water jets.
- Viewing Window: A clear glass inspection window allows for easy viewing of the counter digits and ammeter reading from ground level.
- Installation:
- It is supplied with a suitable insulating base to isolate the arrester's ground terminal from the main structure, ensuring all earth-bound currents pass through the counter for measurement.
- The counter is typically mounted at eye level to facilitate easy inspection.
- Operating Parameters:
- No Auxiliary Power: The device operates passively using the energy from the surge discharge itself.
- Frequency: Suitable for standard power frequencies of 50/60 Hz.
- Working Temperature: Operates reliably in a wide temperature range, typically from -20°C to 65°C.
- Associated Arrester Rating: Designed to work with 220 kV system surge arresters, which typically have a rated discharge current (N.D.C.) of 10 kA or 20 kA (Line Discharge Class 3 or 4)
- The SC 23-1 is a fundamental tool for EHV substation maintenance staff, providing critical data on the operational history and health of the surge arresters.

xplanation of Terms • Voltage Rating : The voltage rating of an arrester is that voltage which can be applied for a limited time after the arrester has absorbed a large amount of energy as established in the operating duty tests. The rated voltage is used as a reference parameter for the specification of operating characteristics. • Maximum Continuous Operating Voltage (MCOV) : The MCOV is the maximum permissible rms value of power frequency voltage that may be applied continuously between the terminals of the arrester. • Temporary Overvoltage Capability : An arrester must be selected with a high enough voltage rating to withstand temporary overvoltages which might be caused by various occurrences on the system. The most common event causing a temporary overvoltage is a single line to ground fault. For an effectively grounded system such faults will normally be cleared in less than one second. Therefore an overvoltage capability based on a duration of one second is usually recommended. Also, the below table shows Temporary Overvoltage Capability for a time range of 0.1 to 1,000 seconds. Arrester Voltage Ratings The chart below indicates the minimum MCOV customers need to specify for an arrester as a function of system voltage. The minimum recommended ratings for solidly grounded systems allow for a temporary voltage rise of at least 40% over a period of one second. Higher temporary overvoltages may require higher MCOV.
