Devices for monitoring current leakage PKTU-1
PKTU device is designed to control the current leakage from the trolley body on the pavement and issue an audible and visual alarm to the driver trolley. The device is installed in the cab and it provides along with control the ability to manage the device power off a trolley bus from the contact network in excess of the permissible value of current leakage in the body of the trolleybus.
