Product Description

The BET-1M, is light weight, cost effective kit, comes handy to measure the Tower earth impedance without isolating the top earth wire. It also monitor substation earth pit just by selecting the mode.In Tower footing earth impedance mode, it effectively checks the performance of tower earthing to handle high frequencies such as lightning / sudden surges and also with high end algorithm checks the low frequency performance to handle high fault current. This equipment is a must for transmission line maintenance team which can help them analyse whether the transmission line tripping could be caused due to in-proper tower earthing design


Tower earthing plays a very vital role and is very important part of transmission line design and has to be periodically monitored to ensure proper operation of transmission line. The tower earth has high dependence on frequency. For low frequency, the earth impedance is a pure resistance and remains constant and equal to DC resistance. At high frequency the earthing behaviour is inductive (the impedance value increases with square root of frequency). Hence tower earthing need to be monitored for both resistance and impedance to safe guard from high frequency and low frequency attacks. Due to top earth wire it becomes difficult to measure tower earthing resistance as removal of top earthing is not possible as it is not safe and time consuming Tower footing impedance tester helps in over comming these problems and also monitor impedance additionally. BET-1M is a must for transmission line maintenance team.
