6 FAQs about [Capacitor trip repair]

What is the function of a Capacitor Trip Device?

A Capacitor Trip Device is used in conjunction with an auxiliary switch to provide for breaker opening from a remote location. It forces the breaker to open when the capacitor is charged.

What happens if a capacitor bank is tripped?

For energization of the capacitor banks, a circuit switcher equipped with closing resistor is used. When a capacitor bank is tripped due to a fault, the circuit breaker is open. The circuit switcher is still in the closed position.

What is the voltage of a CTD capacitor?

Voltage on capacitor will be the peak voltage of input AC waveform. For 120VAC input, output voltage will be 120*sqrt (2) = 120*1.414=169VDC. For DC input CTD, output voltage will have the same magnitude voltage as input. Can CTD be used as a DC power supply?

What happens if a capacitor is charged before energization?

On initial energization, DC power is immediately available even before capacitors are fully charged. Capacitors are typically charged to 90% voltage in less than 0.5s when CTD is turned ON from a discharged state. In figure 2, Thermistor ‘T’ is used to protect against short circuits and overloads.

What is the function of capacitor 'T' & diode 'D1'?

Capacitors are typically charged to 90% voltage in less than 0.5s when CTD is turned ON from a discharged state. In figure 2, Thermistor ‘T’ is used to protect against short circuits and overloads. Diode ‘D1’ performs half-wave rectification along with capacitor ‘C’.

Is ripple voltage a problem for inductive load like trip coil?

Ripple voltage is not a problem for inductive load like trip coil. Only when CTD is used to provide continuous DC power, ripple will be present. See the ripple voltage in figure 4 where a 330uF CTD is used to power 24VA resistive load while the AC input is still healthy.
