A trip point is the value of input voltage that would change the output voltage of a comparator from high to low or low to high. This means that for a zero level detector it needs an input of "0" volts hence "trip point is referenced at zero", so that it can produce change in the output which would indicated that a 0 level voltage is detected.

Zero point is that point where the output function changes its sign i.e. from negative to positive or vice versa.
Trip point electronics means a point on I/p function or variable at which left or right the o/p function changes sign.

A zero crossing detector is a comparator with the reference level set at zero. It is used for detecting the zero crossings of AC signals. It can be made from an operational amplifier with an input voltage at its positive input.

A simple open loop opamp whose one of the terminals is grounded and input is given to the other terminal acts as a zero crossing detector.
