Frequency meter need to connect parallel with the circuit,
as its a sensing device.

there is no such 3 phase frequency meters, measuring from
one phase is more than enough.

Answer / abdul nazir

Same as volt meter connection.
connected parallel with Phase & neutral.

Answer / balaji

phase to neutral

Answer / anugani

Frequency meter connect in parallel like volt meter ((one prob to phase and another probe to nutral))

Answer / munish

frequency meter has no need of three phase.it is connected
parallel with two phases.

Answer / tanmay dey

Frequency meter should be connected across the line and neutral, and the voltage should as mentioned in the frequency meter(generally 120 v).

Answer / waleed ahmed

frequency meter also connected in parllel same as voltage mater install

HELLO EVERYONE, I RECENTLY HAVE FOUND ONE PROBLEM, I WAS TAKING NO LOAD TRIAL OF AN HT MOTOR 920 MOTOR , 1440 RPM , 6.6 KV, WITH AUTO TRANSFORMER. AT 450 V, LOAD WAS 40 AMP AND SPEED WAS 250 RPM. BUT AS WE INCREASE VOLTAGE FROM 450 TO 480V, LOAD BECOME 41 AND SPEED REDUCED TO SOME RPM . SO WHICH PHENOMENON ACTED HERE FOR REDUCING SPEED.?? AND IS IT HAPPENING ALWAYS OR IT IS RARE? I ALSO HAVE FACED SUCH PROBLEM WITH FEW LT MOTOR ALSO.

on 22.03.2015 at 17:15hrs Y phase 66kV class Power Trf-2 Current transformer has flashed over and oil came out. The failed CT has been replaced on 24.03.2015 at 13:15hrs and the Trf has been charged in presence of RT Hassan after conducting the pre-commissioning tests. On the same day at 17:00hrs the commissioned CT has again flashed over and immediately the Trf  has been isolated from power supply. It is confirmed the secondary is not opened and checked the earth integrity and is found ok. Here what would be the reason for the CT failure?
