Load Sharer. 100/110V 1A. The T4800 is designed to control a generator operating in parallel with the grid, or a generator operating in parallel with other generators (which are also controlled by T4800 units). The T4800 will continuously measure and compare the active current on the generator to an external DC reference signal connected to the “parallel lines” input. The T4800 will increase or decrease the speed of the generator (through the governor) if it finds the active current level to be either too low or two high. Two built-in relays provide the increase and decrease pulses for a conventional governor. The strength (width) of the pulses is proportional to the frequency/phase deviation. The E7800 Motorised Potentiometer can be used to adapt the contact pulses to a signal suitable for the speed trim input of an electronic speed controller.

Voltage Relay (3 phase). The G-Line relays are mainly intended for use in land-based applications. The G-Line relays provide an efficient solution for applications where flexibility and cost of purchase are the main issues. G-Line relays provide high quality, proper measuring techniques and a vast number of programmable options.

Optional network-interface and firmware-upgrade communications adapter. Field installs in EL731.

The EFCT series is a sensitive nickel-core current transformer used with Littelfuse relays to detect low levels of earth-leakage current.

G2200 Current Relay. 24V DC 5A. The G-Line relays are mainly intended for use in land-based applications. The G-Line relays provides an efficient solution for applications where flexibility and cost of purchase are the main issues. Despite a low purchase price, G-Line relays provide high quality, proper measuring techniques and a vast number of programmable options. Safety, accuracy and repeatability are important features in any protection system. G-Line relays all have built-in measuring transformers, one for each phase measurement. Transformers provide the best possible isolation with near perfect linearity and thereby no loss of accuracy. Voltages and currents can be measured through resistors or optical couplers.

Reverse Power Unit. B6000 generator protection system is designed for protection of parallel working AC generators. Besides reverse power and overload protection, this system also includes short circuit protection. Optionally, the system can be equipped with frequency detection. The relay can be provided with two extra overcurrent/time units which can be used for alarms and/or tripping of non-essential load. It is also possible to obtain normally energized or normally de-energinzed output relay functions for each of the output relays. Reverse power unit.
