Becker Mining SA electrical senior GM Frikkie Quirk in a statement said, “Becker’s low-voltage relays, with advanced technologies for dependable protection of electric motors used on pumps, fans, conveyors and compressors, can also be used as highly effective standalone cable protection systems to guard against cable theft,”

The new relay systems are capable and programmed to detect cable theft by identifying a change in the electrical impedance of a cable connected to a motor or pump up to 1 100 V.

“In the event of cable tampering, the unit sends an SMS to security, or activates an emergency alarm or siren. This system is capable of supervisory control and data acquisition visualisation and is able to communicate relevant information to a control room through an existing programmable logic controller.”

Quirk further notes that the Becker cable-theft detection system, with real time and date, is able to log up to 1 400 events, providing critical information, including when the alarm was activated and how long it took for someone to respond.

However, he notes that the system needs to be reset at the location of the alarm to confirm response by security. When the reset facility is activated, the unit logs the date and time of the response.

该保护系统需要220 V或110 V功能，也可以用作独立单元，以通过使用用于SMS通信的电池备份设施，通过使用电池备份设施来监控电缆，这为高达八小时提供了PowerBackup。

Proloc and ProBeck electronic relays for motors (which are available in 380 V, 400 V, 525 V, 950 V and 1 100 V, and up to 3.3 kV and 6.6 kV) offer thermal overload protection, earth insulation lockout, frozen or vacuum contact failure and earth leakage protection. Other use-selectable features include short-circuit, frequency and power-factor measurement, as well as minimum load, and over voltage and under voltage protection.

Becker保护继电器还用于控制基于水位，阀门位置，温度传感器，一天中的泵和电机和土壤的水分含量。

这些设备Quirk解释说，还可以检测在钻孔，罐和水坝中的干燥运行，并且可以在指定的时间或设置级别后自动重启泵。

“An important advantage of this system is a door-mounted infrared link that enables a laptop, with Proloc software, to manage all settings and downloads, without having to open the panel door and expose personnel to dangerous live equipment.”

This safety feature, Quirk notes, is a critical requirement of the Occupational Health and Safety Act, although no special licences are necessary for the software.

Becker Mining South Africa offers a technical advisory and support service through- out the country to ensure total reliability of equipment.
