Reproducible Example

import pandapower as pp

import matplotlib.pyplot as plt

def oc_relay_net():
       # create an empty network
    net = pp.create_empty_network()

    # create buses

    # create external grids
    pp.create_ext_grid(net, 0, vm_pu=1.0, va_degree=0, s_sc_max_mva=100, s_sc_min_mva=50, rx_max=0.1, rx_min=0.1)

    net.line["endtemp_degree"] = 250

    # Define switches
    pp.create_switches(net, buses=[0, 1, 1, 2, 4, 5], elements=
    [0, 1, 3, 2, 4, 5], et='l', type="CB_DTOC")
    # define load
    pp.create_loads(net, buses=[3, 6], p_mw=[5, 2], q_mvar=[1, 1], const_z_percent=0, const_i_percent=0, sn_mva=None,
                    name=None, scaling=1., index=[0, 1])

    return net

net = oc_relay_net()
from pandapower.protection.protection_devices.ocrelay import OCRelay

for k in range(6):
    OCRelay(net, switch_index=k, oc_relay_type='DTOC', time_settings=[0.07, 0.5, 0.3])

Issue Description and Traceback

The issue with new version of numpy (2.0.0) is importing Inf, while new numpy need to import inf started with small letter

Expected Behavior

Can`t run any code with this traceback after attempt to impor pandapower
