3 Earth leakage protection systems with self-reclosing Starting from the necessity and obligation of ensuring effective protection to both people and goods and the complexity of installations, requiring continuous supply of electrical energy without removing earth leakage and overload protection, CIRCUTOR has developed a range of equipments which allow safety to be matched with continuous service. Self-reclosing is the ideal solution for installations requiring continuous supply of electrical energy without the usual maintenance staff: Rural installations Cooling chambers Public lighting Mobile telephone repeaters Traffi c lights Tunnel lighting ATM s Cable television etc. In every self-reclosing system, the type of protection to be reconnected and under which conditions, must be known. Self-reclosing systems operate under: Earth leakage current (differential) Earth leakage current (differential) + overload and short-circuit (overload) Elements comprising a self-reclosing system TRANSFORMER RELAY Signal management + measuring and trip BREAKING DEVICE Monitored Earth leakage transformer The earth leakage transformer detects the earth leakage current. This can be placed inside or outside the relay. Self-reclosing relay Self-reclosing relays offer additional benefits (automatic self-reclosing, overload or short-circuit protection), to the reliability and safety shown by U Series earth leakage protection. Its functions are: Fault detection (earth leakage or overload) via a signal generated by the transducer Analyses if this fault should generated an alarm, with regard to the different preset parameters Operates with a power device which connects disconnects the load from the system P2-3

4 Breaking device The breaking element always operates as a power switch. It supports the line power to be protected and is external to the relay. The breaking elements which can be associated to the self-reclosing relays are: Motorized circuit-breaker (MT series) (see page 24) Contactor Disjunctor with remote-control (MCB) (see page 23), with the double function of overload/short-circuit protection and contactor (the funtion of the contactor is bistable) The features to be known from the breaking device are: Rated current (in the contactors) Rated current and protection thermal curve (in circuit-breakers) Features of the command inputs in the operating element Cut-off power NO or NC auxiliary signalling of the status of the breaking device Protection Earth leakage Overload and Earth leakage Reclosing Earth leakage Earth leakage Overload and earth leakage Earth leakage switch reconnector Differential relay + contactor Differential relay + MCB circuit breaker Differential relay + MT circuit-breaker Differential relay + FDE circuit-breaker Page Earth leakage + overvoltage Overload and earth leakage Differential relay + MT circuit-breaker 21 Overload Overload RRM relay + MT / FDE circuit-breaker 22 P2-4

5 Parameters related to self-reclosing relays The indications are associated to the type of protection done, differentiating between instantaneous trip or sealing action. The indications are made in the same relay (LED) and as an option they can be done using auxiliary contacts. Rated tripping point of the protection Typical values: Earth leakage protection 30 ma 3 A Overload protection 6 A 63 A. Timing (delay) for connection Minimum time which the earth leakage must last to cause the relay to trip. Typical values. 20 ms 1 s Relay power supply and tolerance The self-reclosing relays require a permanent auxiliary power supply to be able to manage the automatic self-reclosing. Standard value: 230 V ac (± 15 %) Optional 48 V ac, 110 V ac, 400 V ac. Return to zero time for the reclosing counters In order to avoid accumulations of trips which do not belong to the same fault, a return to zero time for the reclosing counters is set. This time restarts after each reclosing whenever the maximum number of reclosures is not exceeded. Example: The WRU 25 RA relay has a maximum number of reclosures of six before being sealed. In an installation where the transient earth leakage fault lasts for 50 s, the relay will trip 4 times and will reclose 3 times (8 s + 16 s + 30 s). While the third reclosing is being timed, the fault disappears, so the relay will stay on ON. At this time the counter of reclosures returns to zero. The RESET option restarts the relay returning the reclosing counters to zero. Relay status indication Time between reclosures This is the time the relay takes from the trip to the reclosing. This time can be lineal or exponential. Output relay Number of relays With sealing NO or NC output contact Number of reclosures differentiating the type / number Each relay allows a maximum number of closures before being sealed. This counter will beautomatically put to zero if the number of maximum reclosures has not been exceeded during a preset time (return to zero time of the reclosing counters). This number will be different depending on the type of reclosing. On site Test and Reset (using the keypad) and remote The automatic earth leakage reclosing relays offer the same benefi ts as the U series earth leakage protection.very important possibility to check the proper operation using TEST and RESET on the keypad and remotely through the specifi c inputs. The test is interpreted by the relay as an external leak, reconnecting after a certain time and increase the internal reclosing counter. The reset option restarts the relay, returning in the reclosing counters to zero. P2-5

6 Earth leakage protection and self-reclosing EARTH LEAKAGE PROTECTION WITH AUTOMATIC SELF-RECLOSING-REC In most of the cases (95 %), when your earth leakage protection is tripped, a simple manual reclosing solves the problem because there is no permanent leakage. If there is no REC automatic reconnector, this simple, manual reclosing operation may become a serious problem if there is nobody nearby or even if the earth leakage trip is not known: Food rots in the fridge Plants wither through lack of watering Swimming pool`s water goes bad The alarm system does not protect The tilting garage door does not work Your farm may suffer serious damage There is no mobile telephone coverage (fault with t h e telephone repeater) The ATM does not work Streets and squares remain in the dark Traffi c lights stop working etc. Earth leakage protection with automatic self-reclosing Terminals for the command line: N - L: 230 V AC power supply LI: external reclosing order (optional) 2 or 4 pole breaking element Earth leakage protection Manual switch (yellow lever): I position: automatic operation 0 position: self-reclosing not allowed Motor The reclosing counter returns to zero if: Leakage is not permanent When reclosing manually Number of reclosures Time between reclosures 6 10, 20, 30, 60, 120, 600 s Free of power output to indicate the status of the protection Hole for padlock Possibility of manual locking with padlock Earth leakage protection required by current legislation protects people, but unforeseen trips can also provoke the lack of electrical supply in important installations. REC from CIRCUTOR is safe, easy to install, economic and small, and will guarantee self-reclosing in your installation whenever the leakage is not permanent. P2-6

22 MCB.P, MCB.T Circuit breakers The MCB.P or MCB.T are circuit breakers which combine overload functions with contactor functions in the same equipment. The MCB.T version also includes two auxiliary contacts which show the status of the remote control input and the overload input. Both the MCB.P and the MCB.T version include an ordinary contact to indicate a trip from an overload device or from the manual action of the circuit breaker. There are two trip conditions for the circuit breaker: Tripping from overheating, delayed, (overload protection) Rapid tripping, electromagnetic (protection against shortcircuiting) Remote-control operates on the same contacts as the overload device. It guarantes disconnection for any event by remote control after manual or overload device tripping. The remote control operates electro-magnetically, applying a control voltage lasting 20 ms, to the ON terminals (Terminals 1-3) and OFF terminals (Terminals 2-3). It includes an optical displays of the system status (red = ON, green = OFF), regardless of the cause of the trip.
