2.10 ELECTROMAGNETIC ELECTROMAGNETIC COMPATIBILITY The introduction of electronic equipment to perform the equipment control and protection functions in highvoltage substations means that there is a need for high levels of reliability for such equipment, that may not be obtained solely from the use of redundancy techniques, since in an operating environment characterized by high levels of electromagnetic interference, these interferences may simultaneously affect the redundant equipment. Special attention is required from the SUPPLIER to evaluate the requirements of these General Technical Specifications and determine the additional requirements that are considered necessary to ensure the electromagnetic compatibility of the equipment, concerning mainly: - Equipment design and construction characteristics (shielding) as to the capability to withstand the effects of electromagnetic interference. - Cable type and characteristics for connection to outside instruments. - Physical means for cable laying for internal panel wiring as well as for interconnection with field instruments. - Equipment shielding and grounding characteristics. As well as ensuring that the equipment will function in a satisfactory form in the forecasted environmental conditions at the installation site, the equipment shall be submitted to interference tests whose results will evaluate their compatibility with the operating environment. On the other hand, the presence in the field of environmental conditions more favorable than those contemplated in the standard, will not be acceptable as an argument for relaxing any of the severity levels related to electromagnetic compatibility required for the equipment in these Specifications.

2.11 EQUIPMENT CONNECTIONS 2.11.1 General If not otherwise stated, the SUPPLIER shall furnish all power cables, control and instrument cables, rigid and flexible bus-bars, conduits, pull boxes, junction boxes, conductors, cable ducts and trays necessary for effective linkage between all the equipment included in the SUPPLY, as well as all the necessary accessories.

If this is not possible, the multiplying relays shall operate in pairs, one with positive logic and the other with negative logic, fed by two independent electric contacts, with one multiplying function normally open (NO) and the other normally closed (NC). The output concordance indicating a defect in the multiplying relay shall sound an alarm and block the automations.

2.12.2 Automations See Protection and Control Panels Especification.

2.12.3 Electrical Interlocks Electrical interlocks for operational safety shall be made between electrically controlled equipment and in which certain relative positions are prohibited. This type of interlocking shall always be made using at least two normal confirmation conditions, usually equipment position and voltage. Electric interlocking shall be in the form of latent positive action that in the case of circuit breakers, if their closing is electrically prohibited, shall prevent their momentary closing, even with the use of manual or mechanical commands. The electric interlocks may never prevent opening.

2.12.4 Mechanical Interlocking Mechanical interlocking for operational safety will be used when the equipment is physically closed, enabling their use. The “kirk” type interlocking system principle, used for operational safety, is that the key used may only be taken out if the activated device is in certain positions. The “kirk” locking shall not inhibit the opening of the circuit breakers. All starters and circuit breakers, except those in molded cases where it is impossible, shall be furnished with an adequate means for locking them in an open position, thus providing a safe block for maintenance.

2.12.5 Lockouts For the drawout elements of the switchgear, the following lockouts shall be provided: The element may not be moved from the inserted, extracted or test position if closed. An eventual movement shall cause immediate opening. The element may not be closed while it is not in the test, inserted or extracted position. The element may not be moved from the test position unless a mechanical releasing device is manually activated. The element may not be closed unless its main contacts are completely inserted, or extracted at a safe distance. GIS01 – GAS INSULATED SUBSTATIONS

SUPPLIER shall inform COPEL, during the design stage, all the methods, procedures and materials employed in such painting.

3.4.3 Conductors The GIS main circuit conductors, used within bus sections, circuit-breakers, disconnecting and grounding switches shall be made of high conductivity copper or aluminum alloy with the rated current carrying capacity and short-circuit withstand capability, as specified. The dimensions and shapes of the conductors shall be designed in order to satisfy all electrical, mechanical and thermal requirements. The conductors shall be of homogeneous material, free from voids, flaws, burrs and cracks. After machining and before final finishing, the conductors shall be carefully cleaned to remove all dirt and foreign material remaining after any extrusion, milling and manufacturing proceedings. The maximum overall rugosity of the outer surface of the conductors after final finishing shall be adequate to ensure the required specifications of the installation. Connections between adjacent conductor lengths, conductor angle segments, taps and equipment terminal connections shall be made by means of multiple contact, individual spring back-up, tulip cluster-type fingers, mating with stud connectors. These connections shall be designed, manufactured and tested in order to have high current carrying capacity, withstand capability to thermal and dynamic effects of short-circuit currents, low level of partial discharges and resistance to mechanical impacts. All parts of the connections shall be silver plated. The deposited silver overlay shall be at least 20 µm thick. The connections shall be designed with sliding contacts or similar means to accommodate the thermal expansion and contraction of the conductors. The contacts shall be suitably enclosed so as to prevent ingress into the electric field of GIS of any particles generated by the sliding action.

3.4.4 Insulators The conductors and equipment live parts shall be held in place inside the enclosures by suitable support insulators placed at convenient intervals. These support insulators are to hold the live parts in proper position relative to the enclosure during any fault condition such as short-circuit. Some of these support insulators shall also act as gas barriers forming gas tight compartments. The insulating material shall have a high resistance to SF6 decomposition sub-products due to internal electric arcs, to oil and moisture, and shall not show significant dielectric strength reduction during the GIS life span. The insulators shall be free from voids and surface defects, ensuring absence of partial discharges during power-frequency withstand test and shall present a uniform voltage distribution along their surfaces. The mechanical fastening between the insulators and the enclosures, and particularly between the insulators and conductors shall be specifically designed for low corona levels. The insulators shall be designed and manufactured to withstand the stresses imposed by different operating conditions, such as differential gas pressure, overpressures caused by internal faults, unbalanced short-circuit currents and thermal effects of both normal and fault operating conditions. The insulators shall not significantly modify the GIS internal electric field in their proximity. No insulators within the GIS shall be installed in horizontal position beneath any spot liable of producing metallic particles under normal operating conditions. The insulators that act as gas barriers, forming the gas compartments, shall be suitably and indelibly painted on their outer surface to allow prompt and easy identification and location.

3.4.5 Gas Compartments The GIS shall be divided into several gas-tight compartments sealed from the adjoining ones by gas barriers. The arrangement and sizing of these compartments shall allow easy depressurization, dismantling, removal and replacement of any compartment with a minimum action on or disturbance of the adjacent pressurized GIS01 – GAS INSULATED SUBSTATIONS

compartments. The maximum gas volume to be dealt with during service or maintenance of any compartment shall not exceed the capacity of mobile gas handling equipment supplied. The SUPPLIER shall inform the exact gas compartmentalization of the GIS and shall supply a detailed gas service and maintenance schedule for each gas compartment. At least the following GIS sections or equipment shall constitute individual gas compartments: - each phase of the circuit-breaker; - each metal enclosed inductive voltage transformer; - each SF6 / air bushing (if necessary); - each SF6 - insulated cable connection enclosure (if necessary); each phase of metal enclosed surge arrester (if necessary).

All the equipments compartments shall be connected to the GIS with removable links, when removal of these devices require disassemble other parts of the installations. Each gas compartment enclosure shall have a flanged valve adequate for connection of a vacuum pump and gas sampling and another suitable valve for gas density measurement. The valves shall be manufacturer Standard, but set of adapters shall be supplied to allow connection of these valves to the gas handling mobile equipment (LIMCO or DILO type). Each gas compartment shall have sufficient filtering and moisture absorbing material for a minimum of ten years maintenance-free operation. The filtering and moisture absorbing material shall not react with moisture and SF6 decomposition products nor shall introduce any kind of contaminants or solid particles in the internal GIS electric field. The filtering and moisture absorbing material containers shall be removable from the compartments for replacement or recycling. The SUPPLIER shall inform the mass of gas, at rated pressure and 20o C, required for filling of each compartment.

3.4.6 Gas Monitoring System On each gas compartment of each phase shall be installed a pressure gauge and a density monitor (temperature compensated pressure switch). It shall be possible to calibrate and adjust the density monitors in place, without removal. Each density monitor shall have two independent and independently adjustable electric contacts. The wiring from these contacts shall be led to the local cabinets. Each and every gas valve shall have an escutcheon clearly indicating its normal operating position. All the gas piping shall be stainless steel or copper, with welded fittings, vacuum resistant. The contacts of density monitors of all compartments, except the ones installed on circuit-breakers, shall have respectively, the following functions: - first stage alarm upon the density falling to the lower limit of normal operating range, indicating requirement of gas replenishment; - second stage alarm upon the density falling further to 90% of the lower limit of normal operating range. For the circuit-breaker density monitors the contact functions are described in item 4.5.8 GIS01 – GAS INSULATED SUBSTATIONS
