25、s conforming to EN 61050 at voltages exceeding 1 000 V but not exceeding 10 000 V. NOTE 1 Requirements for the installation of earth-leakage and open-circuit protective devices are given in EN 50107-1. NOTE 2 Requirements for earth-leakage and open-circuit protective devices used with inverters and
26、converters are specified in EN 61347-2-10. 2 Normative references The following referenced documents are indispensable for the application of this document.

NOTE Where the terms “voltage” and “current” are used, they
30、 refer to r.m.s. values unless otherwise stated. 3.1 type A device earth-leakage or open-circuit protective device generally designed to be built into the enclosure of a transformer and not intended to be mounted outside a transformer without special precautions NOTE A type A device normally protect
31、s only the transformer in which it is mounted. 3.2 type B device earth-leakage or open-circuit protective device consisting of one or more separate elements so designed that it can be mounted outside a transformer and housed in an enclosure that provides all necessary protection according to its mar
32、kings NOTE 1 The enclosure may consist of the sign in which the device is mounted; the sign having a protection according to its markings. NOTE 2 The device may protect more than one transformer.

Such means might include, e.g. measuring the current reflected into the primary
36、winding of the transformer or measuring a change in circuit power factor. 3.7 sensor device that detects an earth-leakage current or, in the case of an open-circuit protective device, detects when the secondary load current has fallen below the shut-down current limit, and either causes a protective
