METHOD FOR DETERMINING END OF ICE MELTING |
摘要 |
FIELD: power engineering; intermittent deicing installations for power transmission lines. SUBSTANCE: each time when deicing installation is turned on, portion of aperiodic component of melting current is measured and then installation is turned off as soon as this portion greatly reduces; aperiodic component measurement time is chosen in proportion to conductor cross-sectional area so as to ensure equal sensitivity for conductors of all sectional areas. EFFECT: improved accuracy and enlarged functional capabilities of installation due to its application for all grades of wires. 2 cl, 6 dwgr
