G59 Control 52a1t

G59/2 protection is required when a grid connecting embedded generation scheme is installed in the UK to protect against: 

AC Voltage change



Frequency change



Vector shift / ROCOF

On systems in excess of 16Amps per phase G59/2 regulations apply for all UK installations.

The G59/2 protection is provided fully equipped with an internally mounted G59 relay complete with LCD display screen, manual reset button, last trip record & sealable locking facility. 

The G59 relay will automatically disconnect the embedded generator from the DNO grid source upon a mains fault by use of a single or three phase or.



The is supplied with a door interlocked (padlockable) isolator switch for additional protection & enables the to manually disconnect the embedded generator.



A green indicator lamp “connected” is fitted on the door to give quick indication to the that the DNO grid source is connected



Control circuits and relay voltage inputs are fitted with single pole miniature circuit breakers



The G59 relay is of the programmable type with functions to protect against: o

Under & over voltage 230v single phase or 400v three phase (ANSI 27/59)

o

Under & over frequency 50Hz (ANSI 81L/H)

o

Vector shift (ANSI 78)

o

ROCOF (ANSI 81R)

o

Voltage asymmetry (ANSI 47) Positive sequence under voltage Negative sequence over voltage Phase sequence supervision

o

Under & over voltage / frequency has two stage settings to cover short term all well as long term disturbances as defined in G59/2 regulations

o

Adjustable time delay for automatic fault reset (if required)

o

Vector shift & ROCOF protection are selectable to give a best fit for a secure site

o

Five relay outputs can be configured & wired to terminals (at extra cost) to enable a wide range of signalling & trip methods

When ordering please confirm if 1- phase or 3- phase system & Kw rating required. The G59/2 can be used on any type of embedded generator system such as diesel engine / alternator, wind turbine, solar PV or water turbine.

List price (ex works) £ 1220.00 for either single phase 230v (max 14kW / 60A) or three phase 400v (max 30kW / 45A) larger current ratings are available for prices please the office.
