Energy storage of electric operating mechanism of load switch

What is electrical energy storage (EES)?

Electrical Energy Storage, EES, is one of the key technologies in the areas covered by the IEC. EES techniques have shown unique capabilities in coping with some critical characteristics of electricity, for example hourly variations in demand and price.

What is a load control switch?

Meters, tariff and Load Control devices may have zero or more Load Control Switches. When built into meters, Load Control Switches may be connected in series with (a) current circuit(s) or may have independent terminals. The rated operational current of a load switch may be lower than the maximum current of the meter.

What are the requirements for load control switches?

The requirements for Load Control Switches are summarised in Table 23. Meters, tariff and Load Control devices may have zero or more Load Control Switches. When built into meters, Load Control Switches may be connected in series with (a) current circuit(s) or may have independent terminals.

Is a load control switch intended to provide isolation function?

A Load Control Switch is not intended to provide isolation function. A Load Control Switch shall be designed for uninterrupted duty. A Load Control Switch is intended for infrequent use: up to 1 operating cycle per hour. In all applications, Load Control Switches are protected by the downstream (load side) protection of the installation.

How are load control switches connected to a meter?

When built into meters, Load Control Switches may be connected in series with (a) current circuit(s) or may have independent terminals. The rated operational current of a load switch may be lower than the maximum current of the meter. Load Control Switches shall be able to: • carry, make and break currents up to their rated operational current I e

How does load switch integration affect self heating?

‘Self Heating’ is directly affected by Load Switch choice and hardware integration into the meter. Mechanical fixings, riveted joints and semi-shears used on current conductors impede current flow and increase temperature in the meter. Work with your Load Switch supplier to optimise integration.
