5. This secondary is connected to the Honeywell meter voltage inputs as shown in the wiring diagram High voltage CTs reduce the primary current amps to a directly proportional 0 5 amp output As an example a 0 400 amp primary becomes a 0 5 amp proportional signal from the secondary output This allows much smaller wiring to be utilized in the meter hookup The high voltage CT secondary is installed as a continuous loop with a single lead connected to both secondary terminals Honeywell meters accept a 0 2 volt signal from their Current Sensors To convert the 0 5 amp signal the Current Sensors are installed on the CT secondary lead A set of 25 amp sensors is used in this application These sensors have the high voltage CT secondary lead passed through them five 5 times by looping the wire as shown in the drawing This allows a direct conversion of the CTs primary current to a directly proportional 0 2 volt signal which is used by the meter Since there is a signal ratio introduced by the high voltage CTs and PTs it will be necessary to multiply the number on the meter s display for a correct reading The meter multiplier is calculated by using the CT ratio and the PT Ratio PTr x CTr Number of Secondary Lead Passes Through Sensor The Honeywell 25 amp HV kWh meter with 5 wraps of the high voltage CT secondary will have its multiplier calculated by the formula shown below EXAMPLE 400 5 80 1 CTr 80 PT 4200 120 35
