Theearthleakagedetector

詳細(xì)介紹


		The earth leakage detector, approved under section 2 and 3, Article 24 of the regulations relative to the enforcement of the Fire Service Act, is a state-of-the-art digital multi-circuit detector developed for the purpose of preventing fires that may be started by electric shocks or electric leakages caused by the poor insulation of electric equipment on the side where the bifurcation load occur in AC circuits below 600V. The detector consists of visual current transformers (special ZCT) and electric leakage detector. It has been designed to respond according to accurate electric leakage values obtained by blocking the various types of noises, which are present in input signals, with an analog and digital

filterａnd only by converting normal signals. It has an in-built 16 bit micro-processor and can store the operating status of each circuit and time period (second/minute/day/month/year) up to 10 times. The central monitoring PC can monitor each circuit's status with a communication system, and up to 32 devices can be connected through in-built RS485 ports. The communication line can be extended up to 1km and an included monitoring software allows to connect to PC through RS485/RS232 interfaces.
